Hey Marine....there are internet collector groups out there that make, collect, trade, sell. these things like baseball cards.......
I made what these collectors called the "old school" style. I cut two pieces of leather to the shape I wanted, glued and stitched them together, but left on opening at the end of the handle open....and poured and packed the shot from that end. When I was done with the shot, I stitched the opening shut, installed a grommet, I was done.
