I bought this turquoise and silver belt buckle at a Goodwlll in Colordo for 20 bucks. It is marked TRB. I have found nothing on TRB. Maybe it is a Begay, I doubt it is by Tom Billie. I just don’t know. Can someone help me?
Hello. Did you ever find the answer? I just bought a cuff at the Gem and Mineral show two weeks ago, with the very same mark and “handmade” stamp. The seller said it was dead pawn from either the 60’s or 70’s. I paid $350, so you got a STEAL!
