This is a 1954 year, serial numbers matching Model 12 Trap configuration with a Anton rollover stock. Very comfortable, and points nice. 14 3/8" LOP. The gun has been re-blued, and has a Simmons rib. 30" full choke barrel with a .038 bore, with .042 constriction. Gun is still very tight with smooth operation. I would think this possibly is a aftermarket made Trap model. Not sure though. This is a great shooter with some cosmetic flaws, but still a solid gun. The stock had a chip come off the bottom by the trigger after becoming loose while shooting, and has been repaired. Stock was glass bedded afterwards, so should no longer be a concern. The bluing is very nicely done, and some very slight remnants of the previous condition still can be seen on the barrel by the magazine tube. All in all, a very nice solid trap gun that will last a very long time. PM with questions, and additional photos upon request. Asking $650 shipped to your FFL.
