This gun has been stored since i bought it new directly from Sid Woodcock at the Washington Bellevue factory in about 1981. I last looked at it about 2 or 3 years ago and I forget if it is the IV or V but it has the polished stainless flats, 45 cal, have original box, rug, manual, bill of sale,even small bottle of Break Free that came with it. Have extra Detonics mag, ejector, recoil spring, sight blades & wrench, Pachmyer stock ( along with original black wood). Good for collector or shooter but not cheap. Only shot at factory for function and then stored when I went back East for the last 25 years. It was hand picked by Sid for function and fit because I had two previous Detonics that were not 100% and Sid promised to make sure i would have no more problems. It was gone over by his smiths to be sure it was 100% and it never jammed when we tested it. E-mail me direct if interested, I am looking to get about what the new ones go for as it is every bit as good; rostock@cableone.net
