Well I picked up a model 29-3 6" blued with original numbered box and papers at a gunshow today. While at the show I looked the gun over well and it appeared to be pretty much perfect. I paid $650 for the gun but when I got it home and looked at it with a flashlight, I noticed that it has surface rust or freckling on the sideplate and some light rust on the inside of the action as seen when the hammer is cocked. The barrel and cylinder also look very purple/dark brownish in some spots when looked at under the bright light. This could not be distinguished under the "sellers" light of the gunshow, in regular incandescent lighting of my house, or even outside in my car for that matter because it was a rainy day. How badly did I get screwed, and how much can I expect to be able to salvage?
