i have acquired 2 carbine mag pouches,they look to be rubberized canvas?..one is marked on underside of flap,"2" and the other is marked "4"..both have large openings on rear for sliding on belt or maybe on the butt stock of the carbine,,,can anyone give me info on when,where and who these were made for,,,both have the "lift the dot" snaps,,,many thanks,,robert

I haven't seen those before. Are you sure they are carbine sized? They look bigger.
