my neighbor has a winchester model 1, in 12 guage, semi-auto, 2 and three quarter, full choke, monte carlo stock. it is new in box. only been fired 3 times by the factory before packaging. his brother won it at a ducks unlimited banquet in 1960(ish). it does not say "trap" anywhere on it or the box. was wondering if anyone knew what it was worth in 100% condition, so we know what he can ask for it. thanks...
