Guest,
Your rifle falls into the post 64 category of rifles. Winchester made production changes in 1964 to improve efficiency but ended up producing a lesser quality rifle in the eyes of the collecting world. Condition dictates the value function of fire arms. Without some idea if the rifle was stored in the trunck of the car or lovingly cleaned and oiled after every use the range of value is $100 to maybe $600 if it is perfect.
