PAR bolo - Hopi or Navajo?

I am trying to identfy the artist that made this bolo. It looks Hopi in origin to me but I have not ruled out Navajo origin. Has the initials PAR on the back with a tree symbol (see photos). Well made with unusual tips.

This is most likely Navajo made, could not find any information on the hallmark.
