This is a Remington "The Targetmaster" model 510-P rifle that can shoot 22 S,L, or LR. Barrel stamp indicates that this rifle was manufactured in June 1946. The rifle itself is in great condition and has had sling mount added. A little wear on the finish of the stock near the butt plate.
As previously stated the barrel code on this firearm is PRR which is Remington's code for June 1946. This just so happens to be the same month that the Blue Angels made their first appearance under Lt. Commander Butch Voris in Florida. We are not saying that this specific rifle had anything to do with that, but it is quite coincidental that this rifle was created and the same month that the Blue Angels were.
