Larry Ridley had a line of buckles made because he couldn't find any quality buckles anymore. He sells them also, I believe they are cast brass and are around $13 each.
Most people know how to get ahold of him, but if you don't pm me and I can get you in touch with him.
Thanks Tony! I happen to buy some rough from Larry a while ago. I did not know that he sold the buckle blanks. I have his number. Great info, Eric.
Amanda, I will have to check out the links that you supplied. Thanks, Eric.
