Some years ago we had a member decide he was going to make a copy HR. He carved it all from jewelers wax and did a 2 piece ring [skull and band].
Don't think he made many and pretty sure he no longer makes them. They were pretty good for back then. Who knows,,maybe they will be a collectors item in coming years like a Peichel [spelling?]. The better current copies like Hapurs also could become collectors items!, hey, you never know!
