Nice looking field gun, but looks to have been redone, but still a great shooter as they were great pumpguns.
Here is mine, SN is 5 digits, so sometime around 1915, It too was rebuilt into a trap gun by Simmons sometime in the 60's.
It's a back-up to my regular Kolar trap gun. Shoots the same POA and I had the trigger adjusted to be the same as my Kolar.
The Remington Model 31TG below it, is all original. 1946 make, one of the smoothest actions ever found on a pump shotgun.
The Model 12 was bought for $750, the Model 31TG was $850
