These are my favorite conchos but Tandy's discontinued them long ago. I did see them online before but can't now. They are rivet backed, not screw, just under an inch wide, and very inexpensive. The silver color part has light simple engraving. The flower looks brass. I liked them because they were uneven looking and gave the appearance of being hand made. Does anyone here recognize them and maybe have a clue where to find them?
