I have a set of early (?) war smoke candle/grenade launchers left over from a PzKw 38 (t) Ausf B kit, 2 X pack of 3 that mount on the fenders. I'd like to put them to use but as near as I can tell they were of limited use. I have a couple early Stug /PzKw IIIs from France/ Greece time frame and they have armored (?)box launchers on the rear of the vehicles. Soooo .... what time frame and what vehicles would these be accurate for?
