I have looked through a couple of reference books and don’t come across any Benson Boyd. We do get bird pendants that are credited to Benson Boyd from a Raymond Boyd, maybe a family member. I can ask him next time I see him. However, when I google Benson Boyd jewelry it seems anything that has a BB is given Benson Boyd name. I think many of the pieces are just not marked correctly and the seller wants to have a name.
