I have several pieces of handmade southwest style silver jewlery marked "sterling" with a makers mark which looks like a letter "p" fused to the right side of the letter "m". It might stand for Margaret Platero, but in the samples I have seen of her work, the letters are saparated. Does anyone have a suggestion?

Bijoux Amérindiens Ethniques et Tribaux des indiens d'Amérique is a good source.

There are English language posts too.
