Hey Folks, I was watching Mark Feltons Production Videos about Stalingrad and stumbled upon a strange gun shown in a short clip in the movie.
It can be seen at Minute 12:07 as one guy is loading a "hand grenade" in what looks like a 19th century gun
and it also can be seen, being pulled at around 14:02
