I know people use early WW1 airlpanes for their VSF games. Also WW1 tanks are good for VSF. And armored cars as well. But the problem is russians does not have WW1 tanks.
So Mendeleev and Vezdekhod are always an option, but what do you think about twin turreted T-26 M1931?


Here is 1 turreted vesion
I know its 1931 but look at Renault FT-17

T-26 does not look so modern for VSF.

And Also have a look at Char B1
It will look great in VSF French army, because it so close to Renault (only much much bigger)
