I've never been able to get these before from any supplier ever, so when I saw them, I snagged as many as I could. Made of a heavy duty canvas with leather straps and belt loops. These were a more cost-effective alternative to leather ammo pouches, and were used by Polish soldiers in the 1950s in conjunction with M91/30 and Polish M44 rifles. These are in good but used shape and it appears my supplier is already out of these so grab some while you can!
These are not commonly seen in the US at all. I will be keeping one or two for myself.
