1942 production ran to 1287469. 1500001 was struck 1949. Approx. 212K plus guns produced in the war years. Your gun is approx 17K past last documented 1942, therfore you may safely bet the farm it was made in 1943.
If its not anything special, just a production carbine, $500 is a safe bet if its not damaged or altered. Any extra holes drilled for scopes, major bluing loss, stock mods, then less. If its pristine, out of the box like new, a little more.
being a 32 it brings a bit more to the right buyer but joe's about right at 5 bills if it is original and good shape. my dad and uncles all bought 32's in the late 30's and all but my dad still had them until they died. dad traded his off for a rem 141 35 which i still have. i like the old winnies. i'd like to have a 32 to go along with a '39 30/30 i have.
