Silver bear paw overlay buckle, Hopi?

A vintage, loved bear paw buckle.  Silver overlay with a patterned back plate.  The buckle is marked on the back with a conjoined “WC, Sterling.”  I haven’t found that maker but the construction could be Hopi.  Hopi or Navajo, whoever made it, it’s nicely done.  2″ tall x just over 3 1/4″ wide and it would take a 1 1/2″ belt.  Note that the loop on the back of the buckle is a little arched from longtime use.  A great, useable piece!
