This Winchester Model 12 Black Diamond Trap, serial 403409, is a 12-gauge pump with a 21-inch solid-rib barrel bored full choke and fitted with a Cutts compensator, a trap setup that was uncommon even in its day. The receiver ring is marked Trap. Length of pull is 13.5 inches over a vintage elastic Pachmayr recoil pad.

This is a gun for a collector of Winchester pump guns or a trap shooter who wants to break birds with a piece of the sport's history. The short 13.5-inch pull suits a smaller shooter or one who mounts the gun in heavy clothing, and the 21-inch barrel keeps it quick between the shoulder and the target. The compensator and the full choke were the trap shooter's answer before screw-in tubes, so expect tight patterns at trap distances. A Utah buyer is getting a clays gun and a conversation piece rather than a field gun, and the Trap marking on the receiver ring is the detail a Model 12 collector will look for first.
