I was curious about this, and googled it. Is this what was in the original timeline the L3/33?

which you won't know until you go boom?
matilda ii would seem a better candidate.
The Matilda Frog was a flamethrower tank produced in Australia, around the A12 Matilda infantry tank Mk II.

The Australians produced a number of specialised versions of the Matilda, under the overall designation of 'Circus Equipment'. The standard European flamethrower tanks, with a separate fuel container towed behind the tank, wasn't suitable for use in the jungle. The 'Frog' thus carried the flame projector and eighty gallons of fuel within the turret, along with a single crew member.
 
Getting this looked at and sorted early is only a good thing but as mentioned the trade off between building tanks and building spares means you have to choose what gets built.
In time the problem will resolve itself as tank numbers increase and better performance means fewer break down or are lost to the enemy but that isn't an immediate or even medium term fix.
One way to look at fixing the issue quickly would be to get a new manufacturer into to the Valiant group to just make spare parts. The problem is there isn't an easy candidate for this who inst already building other tanks, except one, Vauxhall. Pragmatism could say stop the A22 and get Vauxhall to build spares but that is not a Vickers decision but a governmental one.

The sooner this can be sorted the better and should be an easy enough fix, the only issue will be adapting production to enable the phones to be fitted and possibly making space for new radio's.

Not much Vickers can do on this front beyond getting the 6pdr Valiant out the door as soon as possible in the short term. That should make the tankers happy in more ways than one and the fact Churchill has gotten involved makes it that much easier.

This is an important series of paragraphs. Work starting on AVRE type vehicles makes the later stages of the war so much easier. Plus the time being taken to get them right now means the final Vehicles should be a lot more capable.

Now this should be interesting. Will the project affect the Valiant or have to wait for the Victor? The prospect of a flamethrower tank is a good one but it needs looking at properly. The success of the Churchill Crocodile was in large part down to the fact you still had a main gun, something that wouldn't be possible in the Valiant due to the lack of a hull mounted MG. It would be possible to modify the Victor to have one so that a Crocodile could be built on that hull but making the change to the Valiant at this point in the war is probably too much. The other advantage the Victor will have is thicker armour so the attention it would inevitably get can be managed much more effectively.
The other option is the A22 as OTL but is it worth putting a tank into production for only a limited number of Flamethrower tanks too be built if the actual tank itself is deemed surplus to requirements?

Here comes Percy


All in all another good update, keep them coming. I also assume it was me who made the addition paragraph in the last update necessary, sorry.
Flame Thrower and-or Gun, no problem, enter the Sherman Crocodile,

The spares vs tanks issue is one the Germans had in spades

Its fine if you are able to pick when you are fighting and have loads of time between battles

However its a different matter when the action is happening think and fast or you are haveing to conduct a retreat

Having 120 tanks on day 1 sounds good - until you get to day 5 and you are down to 40 with another 60 that could be easily fixed but you have no spares whilst the otherside now have 70 tanks because they managed to repair a lot of their lightly damaged tanks.

It was exacibated by the difficulty of conducting maintance and repairs on a number of the German designs. The road wheels on a Panther were great for spreading the weight of the tank and reducing ground pressure - but a real pain to replace if it was not an outside wheel that suffered damage.
 

Hard to balance the choices here.....

As you get a specific model heading towards obsolescence in the primary theatre, do you immediately re-build all to a supplentary role for that primary theatre (such as self-propelled artillery), or take the entire inventory of the model and shift them as a group to secondary theatres?

I think the answer is completely dependent upon whom you ask.

If I was leading the forces in primary theatre I would want those obsolete tanks Jerry-rigged as quickly as possible to support my fighting units.

If I was in charge of the secondary theatres or training schools, I would want the obsolete units redeployed as quickly as possible.

Perhaps most important is if I was in charge of logistics, I would be requesting a shift to homogeneous units as quickly as possible to ease the burden of spares in each theatre, so again that would mean a deployment.

Very much looking forward to which of these decision makers Allan will allow to make the final call in his wonderful story.
 
to the list of options one can add keeping the production line active but producing fewer complete units but of engineering models ,more spare parts and moving existing units to secondary theatres.
 
On flamethrower tanks.

To start off with HERE is a video about the Crocodile and how it was used. It really is worth a watch.

First off it is important to note that while suggestions were made to convert Cruiser tanks into Flamethrower tanks they never went anywhere, for the British it was infantry tanks all the way. I don't know of any official reasoning as to why but I suspect the much heavier armour of the Infantry tanks was a deciding factor.
Why waste a perfectly good tank on a flamethrower variant when you have hundreds of marginal use A15 hulls just waiting for a decent weapon? This also applies to AVRE vehicles - it would be nice to standardise on the Valiant / Victor line but if you already have the chassis in production why not use them.
The lack of armour aside on the A15 you have other issues, firstly Vickers won't be the ones making any A15 variant's it will be Nuffield so out of reach of Carden in this story. The issue that waiting for Nuffield presents is that their track record isn't great at the moment. Waiting for them to design something and then fix it's flaws and then get it into production will take a long time. Add in the Logistical issues inherent in adding the A15 to your force creates and I think you have a non starter, yes you can do things like increase the armour by
Bolt some more on, you don't need the heavy turret just a casement.
but that only solves one of the issues and taking the vehicle further away from a tank and stressing the suspension will likely trouble Nuffield to get it right. I really don't see the A15 being used for much ITTL, the production lines could be far better dedicated to building something better anyway.

The critique of
If the bunker has an AT gun capable of penetrating 50 mm armour then it need something other than a flamethrower tank to work it over.
isn't, in my opinion at least a valid critique. You likely wont know what is in the bunker and any flamethrower tank is going to have at most 150 yards of effective range which will be more like 80-100 in reality. At that range 50mm can be penetrated by not only the 5cm Pak 38 but also the 3.7cm Pak 36 so really 50mm is too vulnerable, particularly because the required trailer for the fuel and propellant limit the tanks maneuverability making it more vulnerable. Yes you have the option to attack only places where there are no AT guns but is that really a good way to spend resources, on a tank that can only be uses where there are absolutely no AT guns.

Now given this story so far has only had Vickers looking at non tank AFV's it stands to reason that they will be quickest off the mark with a new design for a flamethrower tank. It will be based on one of their own vehicles, either the Valiant or Victor. Beyond that the Matilda II is not a bad choice but again the logistical issues mean that it would be second fiddle to something that could share spares with the Valiant's, SPG's, SPAAG's and any other vehicle built on the Valiant hull, assuming that is the hull ultimately used. if not then a Victor Crocodile would also make sense as you share parts with the Victor anyway.

Industrialists are chasing contracts here. The government could issue a new requirement for extra spares as a contract, but so could Vickers. Tailor that sub-contract to suit the company struggling to get the go ahead on full production (Vauxhall) and they might regard it as a stop-gap measure to keep the plant busy and train up on tank parts.
 
Looking at the problem to hand (a lack of spare parts), maybe pull some of the suppliers earmarked for the A22 to produce Valiant components instead.
 
I knew that there were some units that I had forgot. From what I understood most of the Garries were rolled into the Lord Strathcona Horse. It is a small world.
Many of the single men were also sent to the 12 RBC, the new Reg Force Unit that in fact replaced the FGH as an Armour Unit....
 
Generally, criticism of the Valiant tanks was limited to cosmetic matters, such as the need for more and better external stowage boxes. What had become apparent however, was the need for an efficient way to clear mines and to bridge gaps, like the anti-tank ditches at Bardia and Tobruk. The need for Royal Engineers to go in ahead of the tanks to remove mines by hand and dig out ramps for the tanks to cross the ditches had slowed the assault.

The Coulter Plough and the Fowler Rollers had already been tested as possible mine-clearance devices. The plough had shown the most promise, but it wasn’t clear how effective it would be on the kind of ground experienced in the desert. The roller system had proven too fragile to stand up to a number of mines being detonated under it. Once parts of the roller were blown off, it was meant to be jettisoned, but that wasn’t easy in the middle of a minefield in the middle of a battle. A joint Vickers/Royal Engineers team were tasked with coming up with ideas. These could either be something attached to a normal gun tank, or be designed as a dedicated armoured vehicle.

Bridging equipment carried on tanks was a well-known and tested capability. During the Great War a 21 feet canal lock bridge, that could carry a load of 35 tonnes had been developed, though not in time to be used during the war. The tank launched Inglis Mark II Assault Bridge, the Batemans Assault Bridge, the Scissor Assault Bridge and the Wild Assault Bridge had all been tested, but lack of funds had left them unproduced. Of all of these, the No 1 30-foot scissors bridge was considered the best option, so another team were given responsibility to work with the Experimental Bridging Establishment to get a working example for full testing, then, if successful, ready for production.

Two other ideas that had come back from the fighting in Libya were firstly, the need for more bulldozers, especially in dealing with the anti-tank ditches. Attaching a bulldozer blade to the front of a tank that could be lifted and lowered into position didn’t look too difficult a challenge, so yet another joint Vickers/Royal Engineers team were given the task of making it happen. Secondly, it was also important for tanks damaged by mines or other reasons, to be able to be recovered as quickly as possible. The RAOC’s tractors were too precious and vulnerable to do this while the battle was continuing. Having an armoured recovery vehicle to tow out damaged tanks would be useful. In the short term, having each tank equipped with a length of steel cable to enable towing was also recommended.

Lastly some Italian Light tanks had been captured which had a flame-thrower capability. For dealing with bunkers and entrenched positions this would be a terrifying weapon. To design such a weapon was task that would take some thought and work. More information about the Italian tanks was requested to see if they had come up with simple solutions to complex problems, rather than the Vickers team having to begin with a blank piece of paper.

One of the questions that all of these types of specialist tanks raised was whether these should be issued to the Royal Engineer’s Field Squadrons attached to each Armoured Division, or whether the Royal Engineers would be better off having their own specific Armoured Brigade, perhaps called an ‘Assault Brigade’. At some point the British Army would need to consider how to invade Europe. All these different types of armoured vehicles, and more, would be required. Putting together a team to discuss all of this was recommended to the War Office, which agreed. General Percy Hobart had been pestering friends and acquaintances in the War Officer for a job since he had come back from Egypt and retired. Someone in the War Office saw this as a perfect opportunity to kill two birds with one stone.

So, they are looking for mine clearing equipment. Mine flails were the most well-known and impressive OTL solution. I struggle thinking of anything better. I am assuming thus that they will be the go-to solution here as well? Also, that's a thing one can put on a tank to make it ever more frightening to enemy conscripts.

Also, flamethrower tanks, woo! It's interesting that the Italians primarily used fairly light tanks for that role, whereas to the best of my knowledge, noone else thought that would be a good idea.

And Hobart getting to setting up his 'Funnies' earlier. This can only be good.

Why waste a perfectly good tank on a flamethrower variant when you have hundreds of marginal use A15 hulls just waiting for a decent weapon? This also applies to AVRE vehicles - it would be nice to standardise on the Valiant / Victor line but if you already have the chassis in production why not use them.

not enough armour to get close enough for the flame to be effective.

What mr Tuomi said - a flamethrower tank needs to get close to the target. to be effective. If the man-portable weapons which can kill it are relatively rare and have a shorter maximal effective range than the flamethrower, it has enough armour. A lightly armoured cavalry tank is a lot more likely to be killed by a lot of things. I am fairly sure that even the biggest anti-tank rifles can potentially penetrate a cavalry tank from certain angles. For AVRE types not meant for direct combat like bridgelayers, it's a different matter.

That said, because the Italians are using lightly armoured flamethrower tanks, if the idea is rushed into production the A15 might be used, I am hardly the #1 person to tell here. I don't think they will persist with A15-based flamethrowers though once they start losing them.

The other option is the A22 as OTL but is it worth putting a tank into production for only a limited number of Flamethrower tanks too be built if the actual tank itself is deemed surplus to requirements?

Making the A22 with the standard variant having a 6-pounder turret and a hull mounted flamethrower is not a terrible idea. It will at the least have a niche of it's own. Ideally, if this idea is incorporated while the tank has been sent back to the drawing boards, the flamethrower fuel will be stored not in a trailer but either an internal tank or something similar to a more armoured variant of the external fuel tanks.

That said, a Matilda Frog-alike is probably the best bet, as it gives potentially already extant Matilda II's which are judged to have too weedy a main gun a way to actually be useful on the front lines well into the war.
 
Parts and spares could be requested of Canada as in isolation they would be much easier to produce than completed vehicles.
