I turned 10 years old in August 1959. For my birthday my dad handed me his 12 gauge Remington 870AP Wingmaster and said, "It's yours now, son." To me it kicked like a mule. My shoulder would turn black and blue for a week. To my surprise, at Christmas that year I unwrapped a gun case that had my name on it. Inside was a Remington 870AP Wingmaster 20 gauge with a 26 inch Improved Cylinder choked barrel. The barrel code PZZ indicated it was made in June 1953. My dad told me, "This one won't kick as hard."
I can't tell you how many doves, quail, pheasants, squirrels, and rabbits I harvested with those 2 shotguns. They have never failed during 5 1/2 decades of use.

The two 870AP Wingmasters still alive at the end of 2016. I plan on their continued use for several more decades.

This Remington magazine advertisement from 1950 showed that a first year production basic 870AP Wingmaster pump would set you back $69.95. And the higher end 870 ADL Deluxe High Grade would cost you another $10. Still a pretty lofty price for back then.
