Hey guys I'm both new to the site and rather new to collecting. I recently purchased a lot of knives from a local auction that included this Parker knife. It has no model number that I can find so I'm having trouble identifying it. The tang is stamped with Parker then an eagle and the usa. It is a single blade lock back with what appear to be smooth white bone or possibly and imitation. Also has a round brass shield with the words Parker a picture of an eagle and usa. It appears to be unused and comes with a leather sheath. Can any one help? Sorry not sure how to use pics yet
