I think I can help you out.
If you are looking for a simple leather band that laces at the bottom of the stock and holds cartridges in loops along the side that's pretty easy. I need the diameters of the front and back of the band and the length of the band. A pic of the side of the butt stock would also be handy. I would charge $30.00 and it would be ready in a week. All leather is top grade and all stitching is hand saddle stitch. I can throw on an initial or three at no charge.
