I have an engraved Colt SAA made 1925, a 1 gun shipment to S.F. It is heavily overlaid in silver, top, bottom, sides, back, and front. The silver is engraved. Gun and grips are in excellent condition. I was told it was done by Adolph Bayers in Texas about 1940. The engraved silver and gold grips are hallmarked Newmans Silver Shop Reno (circa1935-1955). Does anyone have any other information that may be of interest? http://s1187.photobucket.com/user/woodsawnevada/media/MEMO00012.jpg.html
