my dad left me a Winchester model 37 STEELBILT-12GA. I know from listening to the stories he picked it up from the back of a friends pickup in the 50's. it seems to be in complete working order. I want to get rid of it as i have 2 small kids and no where to lock it up for saftey so if you could advise me on how one goes about selling a gun in NJ. thanks in advance
