Crime Thrillers - Seventies - British.
In my opinion, one of the coolest guns on the cinema screen was the Model 1932 Mauser Scnellfeuer Pistol. 7.63mm selective fire pistol. Showed up in severl seventies crime thrillers, all British productions:
1. Sitting Target - Oliver Reed, Ian McShane
2. Brannigan - John Wayne, Judy Geeson
3. The Disappearance - Donald Sutherland, Christopher Plummer
This particular prop gun came in a fitted case, with 1 ten round magazine, 4 twenty round magazines, a shoulder stock, and even a telescopic sight.
Two pics below from Sitting Target ( a British crime thriller in the 'Get Carter' genre), where it was wielded through most of the film by Oliver Reed.
Neat package! Maybe not practical, but it looked great in the movies.
