I wonder if Empress/Under Fire will do period French (Empress already do a Hotchkiss M201)?
The infantry would be nice, especially since they could be used for Beirut and Africa. Pretty much all you want vehicle vise can be found in Solido or QuarterKit/Gasoline and of course Quarterkit make conversion pieces for the Solido Verem diecasts. Very nice models the Quarterkit stuff. Highly detailed, superbly cast and surprisingly easy to build. Just needs infantry. The other route would be to lobby Eureka to back date their FFL.
