Winchester model 1912- 12 gauge pump action shotgunnickel steel

This shotgun was handed down to me from a waterfowl hunter over 30 years ago. Only used a handful of times since. Well used but works perfectly and kept cleaned and stored in humidity controlled gun safe.  Serial number is on the barrel and action. 

Last manufacture dsye on the barrel is  1913. 

2 3/4 12 gauge , full choke.
