One year of war ... no tank building tradition, experience or know-how. Probably you will build a little monsters and first tank if you start with you own design in 40' will be on production lines ... maybe in 42'.
Start thinking about tank development or use in Haram from mid 20', then you will have a knowledge to build armor and not take bazillion of models from your hat in just one year.
hm.... thinking a bit.
I can see a possible way for Haram where they build their own armored trucks and cars, and purchased tanks from ... shall we say, the U.S., since they built quite good tanks during these periods, or shall we say. bought tanks from the British and later went over to U.S. tanks and finally to self-produced tanks.
and i agree there must be some ridiculous tanks developed during this time. but how they shall look like, I have no clue. but we can for example say Haram have had a slow development on producing there own tanks. So let us say Haram have had about 5 to 10 year with testing and failing before they got it right (espionage), then started to develop and build tanks in small numbers, Before on of the many large Haram industries started to build.
With this we can say: research an development 1920 -1930, Small number production 1931 - 1940, Industry taking over 1941 -.....
so concept that is stupid is welcome, but also tanks that was build and are a bit odd, .....
