I would guess someone even in the old days made some antler grips on a percussion revolver. I have some old legal ivory bought from Boone Trading many years ago that I used on some knife handles. It was just not enough to make two revolver scales, or I would use that. I can't believe so many manufactures hide beautiful walnut under bad finishes. I had to use the same stripper on my M29 that came with a thick high gloss tinted plastic finish. Here is the result on just the grips after the stripper shed the stuff off in large sheets of plastic. It did not look like real wood before. I did make some better walnut grips from some really old wood on my Colt Pocket Model in this picture. The original walnut was very pale and plain and I'm not sure if it was actually Walnut.
