Winchester 1897 pump riot shotgun ser# 296799 what year made?
Winchester only sold pump rifles which were chambered for various .22 rimfire cartridges. If you have a Winchester 30-30 pump rifle, its value is tremendous since all 30-30's were lever action.
The 1400 is not a pump. The pump version is the 1300.
I would need to know the Winchester model number,and the overall condition to give you a accurate value to your Winchester.
50-150 USD
