I haven't owned a color case hardened revolver for a long time. About 30 years actually. I was looking at an old model Vaquero yesterday at the local gun shop with intensions to buy. A sweet 7 1/2" 45 that is still calling my name. The reason I put it back was a large spot on the left recoil shield that either wasn't ever colored,or it "came off" in some manner. Is it possible to have this type finish "come off"? Or, was it just missed in the process? It almost looks like there was an oil or other contamination that prevented it from taking color. Like I used to get when I tried to cold blue as a kid. Anywho,I could just call it character and head on out and bring it home. Dang it sure felt good in hand.
