Model 12 Super Grade.

[Grantham Forester]

I have my Great-Grandfather's 20 gauge Winchester pump-- but it is stamped Model 1912. It is a field gun with a 25" long barrel with matted solid rib and a Modified choke. He shot doves and quail with it in GA before WW2- When did Winchester replace the Model 1912 with the Model 12. My gunsmith said the Model 1912's had shorter chambers in the 16 & 20 gauge guns, and when Winchester re-designed it into the Model 12, they made the chambers a std. 2.75" long for the more modern shells-
