rgg 7,
I drew up the plans myself, to fit this specific gun, The walls are solid oak that I planed down to 3/8" thickness. I used some 1/4" oak veneer plywood for the top and bottom, just because I had it left over from another case. Any old plywood would do, as it doesn't show anyway. The leather is from a deer that I shot a few years ago. I don't think that I would use deerskin again as it is somewhat delicate and demands careful handling. A piece of 8 ounce, vegetable-tanned steerhide from Tandy leather would be a lot more durable. All of the hardware is from Lee Valley Tools. If you don't have them already, send Lee Valley an email and ask them to send you both their tools, and their hardware catalogues. Great stuff!

It would be nice if there was a book out there which showed how to do this job, step by step. I am unaware of the existence of such a book. I was forced to learn how to do the interior, when I bought a case which arrived damaged and had to gut the interior and recover it. It was a good learning experience if nothing else.
