I sort of inherited a FWB300s , it has no metallic sights, it has a cheap Simmons scope mounted. Condition is about 90-95 percent or so. I know it has been in a closet for the last 20+years without being fired, so it very likely needs an overhaul. I don't know what these things are worth, so am curious as to whether it's worth it to send it in to someone to tune it up, might keep it if it's worth it. Thanks.
