I have had so many PM's asking about where I got the clasps, that I thought I would post it here. I bought them at a local leather supply store that does mostly mail order business. Here is a link to the clasps on their website- http://www.leatherfactory.com/products.asp?number=1304-04
I took the clasps and all 3 of my cases to a local shoe repair shop who replaced the clasps and the leather patches on the inside. They charged me $15 per case, and they even replaced some of the tacks that had fallen out of the bottom edge of 2 of the cases.
