To produce any model kits in plastic, we do need to sell a fixed amount of kits to break even.
The quantity will depend on the number of sprues required.
For gaming purposes, to decide what vehicles to produce and for which country, we usually
will study rulebooks for several popular game systems, plus army lists used by most players
of each system as well.
For minor countries such as France, French-made tanks are only available at the beginning
of the war, these tanks are usually of mid-30s design. The Renault FT is even earlier in 1918.
For some early war tanks, some will survive and still be used towards the end of the war,
but usually in small war pockets as dug-in pill boxes or for city policing and defence.
We have been studying French tanks (plus for other minor countries), and had one or two
tanks that are more favorable than others; but this list will change as updated versions of
popular game systems are released.
Right now, for the French, we have the Hotchkiss H35/H38/H39 light tank and the heavier
Char B1 bis on our list.
