Win M-70 going price
I don't know how many gun shows there are in your area, but just like with used cars information is power. I would go to the gun show and see what they are ASKING for ones on their tables that are similar to yours.
The Win collectors that I have met all can spit out tons of information on various features and can probibly tell you a lot about your rifle. I would have the rifle in the car, and cruise the show prior to bringing it in. DON'T
sell it to the first dealer that offers money for it. If they want it immediately for x number of dollars they will still want it for the same money in an hour. I have seen rifles/pistols sold for less then they should have been. The tables closest to the door are the prime locations for getting walk-in guns as they come in. Good luck, consider strongly keeping it prior to selling it. I regret almost every rifle/pistol sale I have made.
