This is a Leather Flintlock pistol holster inspired by the ones described in 17th/18th Century books about Pirates.

It holds the larger replica guns such as replicart as well as the smaller denix style ones. The holster is fastened together by leather thong and either 3 brass rivets or 3 period correct copper rivets. It features a skull and cross bones at the top and a decorative rivet at the bottom (which can be left off the design if required) along with 3 decorative straps and buckles.
