WC145, I'm going to take my wife's billion dollar camera and get some good pictures this weekend and post them, along with the Hi Power.
Here is what Colt's custom shop manager said in a PM -
"I think that's all in the photo taking.... Same polishers I have had, bluing salts haven't changed, equipment hasn't changed. Only thing I will tell you is it changes over time as it ages, it will get more of a blue tint. Bluing changed from the Python days but it has been a long time since any process change. You can try to renaissance wax or a light polish with flitz to bring out the shine.
