Help with maker, value etc. any information is appreciated large cuff & buckle

I interited these from my father. I think he mentioned they were Navajo, Running Bear? I remember him purchasing them in the 70’s


I can not tell from the picture if the hallmark is a JP or JR. These are classic 1970 pieces, nugget style turquoise and lots of silver. In town we have a shop called Running Bear that makes lots of jewelry, could be place of purchase?
