Thanks for the replies, everyone
Armored trains will be coming along eventually. No time table yet.
The trains depicted are German. I eventually plan to include French and Russian trains, but I figured I would start with German. For WWII they would be, by far, the most common sort of rolling stock you would find. After 1941 you would find German trains everywhere, from Norway to Greece, France to the Ukraine. So this kit would be appropriate on just about any WWII gaming table. And as a note, while doing the research to make these I noticed that there was actually very little difference between countries when it came to things like box cars. A German box car looked like a French box car looked like a Dutch box car looked like a Belgian box car, etc. etc.. I'm sure an expert could tell the difference, but I made this kit for gamers who wanted to add something different to their game table, not for model railroad buffs.
