I enhanced what I could on your bracelets etched signature, sometimes these are the hardest to read & identify so don’t give up yet.
Could it possibly be “P M Vincent”? That is just a wild stab in the dark but it’s what came to mind when I first looked at the pictures.
could it be P. Mir???
Thank you soooo much Steve, that’s very kind of you to take the time to do that.
