A buddy on another forum gave me this .36 Remington Navy after my guns were stolen. Made in 78 with a capital P over a capital R and FIE on the butt and a three digit serial number. PR is a new one on me and the bluebook site is no help, neither is google. Haven't shot it yet but won't be long. Those .36 balls are soooo tiny. He also sent a custom holster, 100 balls and wads and the neatest lil cleanin kit you ever saw.
