I think the basic idea, using a bodge of COTS parts to make a tank sounds like a good idea, but this result is Type 95 Ha Go territory.
Not a Ha Go. A
CTMS-1TBI tank?
Definitely a Type 95 Ha Go. Both are decidedly not going to impress; but it is better than nothing.
Few prewar light tanks did impress.
At the bottom, was the 4 ton Vickers Light Mk.V
12mm armor, with 15mm and 7.92mm MGs, but speedier than the rest at 32mph from it 88hp gas engine. 3 man crew.
Then the Panzer IIB, almost 8 tons, 16mm armor, 20mmL55 autocannon and 7.92mm MG, 25 mph, 130hp gas engine, 3 man crew. It's best feature was the first German tanks where most had radio transmitters as well as receivers, unlike the PanzerI
L6/40 almost 7 tons, 15mm armor, 20mm autocannon, 8mm MG, 26mph from a 70hp Diesel, I believe. 2 man crew
The Ha-Go was 7.4 tons, 16mm armor, 37mm cannon and two 7.7mm MGs. 28 mph, with an 120hp aircooled Diesel, best of the lot on that front.
French H35. 11 tons, up to 40mm armor, a weak 37mm and 7.5mm MG, 22 mph from a 120hp engine. Two man crew, no radio. I have said some designs were eggshells armed with hammers, but this was a tortoise armed with a pointed stick. Not much more than a faster Matilda I.
Last the Marmon, that was 10 to 11 tons depending on the exact version, 13mm armor, a 37mmL44 semiautomatic cannon or twin .50s,plus four more .30 MGs. 25 to 30mph, with a gas 174hp or 123hp diesel. 2 or 3 man crew.
Now early light tanks that did impress was the US M2A4, from high speed, reliability, 25mm armor and good 37mm gun, plus the best radio gear of anyone, and the Soviet BT-5,very fast, mostly reliable and a powerful 45mm cannon. Few had radios.
