The box I made myself from examples I found in sketch book '56 from the French and Indian War Period. I liked the banana curvature of the waist belt cartridge boxes, but I wanted the shoulder strap style. I wound up making a pine block and drilling 27 holes into it. Then I made the box from heavy natural cowhide, wetted it and turned it inside out. Two inch linen straps were sewn on, I did not incorporate any length adjustment to keep things simple. For the double lid, I made wooden sides to the inner lid, wetted it and banded it down till it set up pretty tight on the radius, then I made the larger cover lid and the brass stud on bottom to hold it in place. It turned out to be a pretty nice fit on my right hip, good for sustained field use if the British should ever come back : ). As an American, you can take liberties with the box, the styles were all over the place. My box is a conglomeration of styles that appealed to me. Thanx for asking!
