I wound up with a nice 760 pump in 35 rem. It is almost perfect with the only signs of wear being on the pump slides. No dings or scratches and perfect blueing. It has ZZ stamped on the barrel which should mean it is a 1953 second year of production gun(according to 1 website). Its not been drilled for scope or sling swivels, seems to be 100% original. What would this be worth? Any kind of collector value? Just curious, as I already have a decent chunck of change in this gun.
