Model 12s were first in 20 gauge only. The 12 and 16 were introduced in 1914 ( catalogued 1913) making this a first year gun to the best of my knowledge. They were 2 9/16" chamber in the 16 until 1926 or 27 unless the chamber on this has been lengthened. Rst and possibly others make great shorter shotshells for the older guns.
No markings anywhere on the barrel, but a 2 3/4" shell fits in no problem. I have not fired the gun yet, what could happen if its chambered for 2 9/16 and I fired a 2 3/4" shell from it? There is no lip or shell stop in the barrel, its smooth all the way out.
I had one marked model 1912. It was 2 9/16. I reloaded For it using plastic rem and federal hulls shortened. Had a slight opening on top that I filled with wax. Nice light easy to carry guns. Good luck with your sale Jeff
The 20 was first made in 1912 , the others were added in in 1913 . My 16 was shipped in 1913 . 1914 would be a second year 16 with 2 9/16" chamber , not marked . As far as I know all pre WWII shotguns and many made after but before 1950 were for what we now call short shells .
Grumpy old man with a gun.....Do not touch . Better to be judged by 12 than carried by 6. Don't bother my monument and I'll leave yours alone.
The 16 g was first added to the catalog in 1913 , none were produced before then . If you had a 1912 made in 1912 it would have had to be in 20 g . You got some bad info .
