Thanks all for the great tips. I am in contact with Austin, and have ordered my .010 brass sheet from an ebay vendor, Sloan. And Karl, I will keep your techniques in mind as I give this a try-your brilliant restores always inspire me to do better.
Marty, for the bone or similar component, I actually have a drawer full of old antler sheds, elk antler, and even some fossilized walrus ivory, all of which came with the complete knife-makers shop we bought out years ago when we though my son was going to be a knife-maker. I have cut a "slice" from the base of one of the antlers, and may go that route. But the ones I have seen with a dark interior piece (dark horn or hardwood) also look very nice. I've got plenty of dark horn and hardwood scraps (rosewood, ebony, ziricote, etc.).
Once I get the scales cut and shaped, I'll probably lay out my wedge options along with the brass and see what looks best-yikes, I guess I'm committed to this now!
