121
The value of a Winchester 121 22 single shotgun depends on its condition. As of 2014 these sell at auction for around 160.00 in excellent condition.
its worth about $70 depending on how beat up it is.
All Model 121 are date code stamped, see related link for details. Like a car if it's in the junkyard or in the showroom for sale they have different values, need a good description of condition for valuation.
Manufactured: 1947, value dependent on condition. I bought a model 121 fieldmaster brand new in 1954 and they were supposed to be the first hammerless pump . I do not know what year they originated but , now you know it was at least in 1954 or before . Wish I could pinpoint it better for you but you now have a jumping in point.
