The rifle on Mel's site does really qualify as a brass box w/ wood insert, as the box lid is a heavy and fairly thick casting made specifically for a wood insert. Kind of like a rectangular tray. If I remember right, and I'm not sur eI do but I think I do, the brass inlay on top (in the wood) is a like a washer which holds the wood in place and is screwed or riveted to through the wood and casting like a toothpick in a sandwich. I'll have to go take a look at Mels site again. I think that box is one of the neatest things going!
