Art,
I appreciate your reply. I figured there must be a specific anvil needed since that is what a rivet requires to be set. I don't have metal working skills, but suppose I could try to fashion something to fit this acorn stud.
Neither source I have found have been very helpful about setting the stud (names intentionally withheld). Seems like either company would be selling correctly shaped anvils as well.
I may just try and use a Sam Browne stud or a button stud, but neither are correct for the period. My local leather store carries Sam Browne and button studs so I guess I could look further into this option.
If anyone has further ideas I would love to hear them.
