Four leather magazine pockets alongside a sewn-in leather shoulder strap. This design was engineered by Yugoslavia during the Cold War to hold four curved 35-round magazines for the Yugoslavian M56 submachine gun, a blend of both the German MP40 and the Soviet PPSh-41.

Fits:
- 35rd M56 Magazines
- MP40 Magazines (9mm): Standard German 32-round straight magazines will slide into these cells perfectly but will sit deep. 

- STEN / Sterling Magazines (9mm): British STEN gun or Sterling submachine gun straight stick magazines

- PPSJ-41 / PPS-43 Stick Magazines (7.62x25mm)

There is writing in marker on the back of this pouch. Someone at one time wrote:
WWII Real PP 38 + 40 Mags

Dimensions: 10 1/2" x 6 1/2" x 2"
