There were a lot of different version of these in various materials. The one posted by kass is a classic example. sometimes you also have an additional very thin and long strip of leather to fasten the ammo. I have see over 20 of them and yours have exactly the same materials (leather and pins) as were used in the ones that I have seen (dug-ups). However the form of the front board (wave shaped) is new to me. Light brown and black are the most popular, but there are also green versions made of artificial leather. The dug-up are not that rare, but a poach in a good condition is hard to find. Great item to have!
