New to the forum an just bought a H&R 223 rifle today, but I have a old to me but looks new 20 gauge NEF shotgun. Gun was bought new by me in 1990 per serial # shows 90 model. I bought this for my son to go dove hunting with me back then an to learn about weapons. Gun may have a box of shells or less shot threw it. It is in very good condition but not excellent close though. Gun has been kept cleaned during the years but no use. My son will probably never use it as he has my 870 wingmaster an just won a over under shotgun. So the gun is just wasting away. What would be a fair price to sell ?
