So a derivitive of the Skoda 38? The Pz-38 was a pretty decent tank for the era. When I was giving tours at the U.S. Army Ordnance Museum I used to love showing off the Skoda 35 we had (It is now back in the Czech Republic) Both the 35 and the 38 were used by the German Army and made up a significant portion of the forces used in France in 1940. The 38 was also used for several antitank vehicles including the Hetzer which stayed in use by the Swiss long after the war.
The problem with using a design developed elsewhere is getting production drawings into a format your industry is familiar with. It is bad enough with a light weapon like a machine gun but a weapon as complex as a tank has many levels of detail (engine, transmission, main weapon, etc) that need to be converted and produced. It is difficult enough when you have the full cooperation of the originator (such as the Americans producing a British weapon such as the 6 pdr, the Bofors 40mm or the Soviet T34,yes that was requested by the Soviets and a sample vehicle provided) But if the Brittish had started the process of producing a Skoda tank there would have been problems after the Germans invaded Czechoslovakia in getting cooperation of Skoda in resolving any issues. Most of the issues could have been resolved eventually but it would have taken time which was something the British didn't feel they had time for. The 2 pdr was kept in production even after the 6 pdr was ready for production because they didn't want to reduce the rate of production to convert over.
A major problem with British tanks of the early war era was a requirement that they fit within the standard loading gauge of the British rail system. This limited the size of the turret ring which limited the size gun the tank could use. The Skoda designs did not resolve this issue.
The biggest problem the British had early in the war, especially in North Africa was not equipment but in tactical doctrine. They had a hard time adapting to the new combined arms methods that the Germans were using. I believe they would have had trouble if they had had Shermans, Cromwells, Comets, or T34s.
