That's really slick Mark, good idea. I've been looking into these kind of things too in order to get a complete restoration. Bothers me sometimes when you lose the little details like this, I get what you mean. There are some slick stuff out there now. It's easy to make your own water slide decals at home using an ink jet, can get very small. For stamping, like you just did, I saw a stamp making machine, used by scrapbooking people mostly, but havent tried it yet. It's very cheap, I think like $40 for the system. Think it work really well for something like this and no carving needed!
