I recently acquired my first P14. There are no WRS marks. It's in fine condition, all matching numbers and Remington marked parts. Barrel is shiny and bright. Believe the stock is a replacement due to no markings on the butt stock. The bolt may be as well. It's only marked Remington on the cocking piece. It was imported by Springfield Sporters of Pa and still had their hangtag. Their stamp is underneath the hand guard.
I posted photos on the Enfield Rifle forum. They said they did not specialize in P14s and recommended I pick up Charles Stratton's book which I have done. He states Mk I "rifles in original configuration will fetch a several-fold premium". How close is this example?
