My local shop has a used Model 83 Premier Grade in 454 for $1199. It has a 7.5 inch barrel and is in good overall shape. The barrel crown looks good, although the bore has some copper fouling in it. The box that goes with the gun is brown, not blue like the current ones. I'm wondering how old it may be. The shop says it hasn't many rounds through it but of course its hard to tell. I held off on buying it today because I'd really like a 6 inch gun. What do you all think. Is this one of those super deals I shouldn't let get away? By the way, no manual with the box. Opinions appreciated!! Thanks guys.
