That I happen to have 2 M-12 Trap guns. One is a first year milled vent rib gun(1919) and the other is a solid Rib trap gun that I got at an auction in Cody last year(250 bucks)...and I still have that ol 12 ga I got so many years ago. It sure do be very well used and a little ugly. It has had over 400 thousand shells through it since I acquired it. I have also acquired over the years 2 other front ends ..one in 26 "IC choke and a 30" Full choke..original gun was 28" mod. According to the serial it is a first year 12 ga(1915). First year or 2 they only made 20's ......and a few 16's I have been told. I have had a thing for M-12's over the years. Bought and paid for my first house years ago with the money from selling a bunch of M-12's

But it WAS worth it...I guess!
