10662XX plain barrel 12 is marked SKEET under the serial on the receiver. Serial matches on the mag tube; top rear of barrel and receiver both have the Winnie proof in an oval. There is no choke mark on the barrel anywhere and there NEVER was. Cutts comp. and collet choke mech butt to a flange turned on the barrel. End of Cutts with the collet run down to full choke to bolt face: 27 3/8". Total length Cutts comp. and choke collet: 5 3/4". Subtracting steam whistle from total: 21 5/8". Overlap of compensator on barrel in front of flange: 9/16". Total barrel length: 22 3/16". Total effective length of the whole lashup for swing wgt. and all that kinda stuff is as above 27+". I also have a later '41 m12 with an overbore (roughly 10 ga.) Barnes barrel and vent rib on 12 chamber and Colonial Arms choke tubes. Got a cheap Sile Monte Carlo on the back. Swings a lot easier than the official plain barrel model from the early 30's. I am married to this one for the one single thing about a gun that brings the most satisfaction: I'm a consistently good shot with it. I have the other one to admire the crotch walnetto and laugh to myself every time the "ribbing" starts about Winny and AfterWinny cause whether this "factory skeet" is worth anything or not, it is unquestionably "factory". How ya like them fish?
