I'm considering buying a revolver from a friend of mine and want to figure out a fair price to offer him. It's a Taurus "Old" Model 66, the six shot version, approximately mid-80's production I'm guessing. 6" barrel and stainless steel with wood grips. It needs some TLC, has some stuff on the outside of the barrel that needs to be cleaned up and needs one of the screws for the sideplate that locks the yoke in. The cylinder has a slight rotational rattle at lock-up, but the chambers all align properly and the timing is spot on. Trigger break is good and the bore looks in good shape other than needing a good cleaning.
The guy I would potentially buy it from is a brother from my motorcycle club so my goal isn't to screw him down to the cheapest possible price, but to arrive at a fair price that good for both of us. So I'm looking for some help on a value for this wheel gun, any ideas?
