Ok, hang on a sec......
There is nothing magical and no sorcery involved that makes a python shoot better than any other gun. What makes pythons pythons is the fact colt doesn't make them anymore. Prior to colt putting a halt to regular production of them in the early 2000's you couldn't give them away for $550.
Yes, they have a great trigger pull, yes the early blued models are gorgeous, yes they have a following.... But don't for one millisecond think they shoot ant better!
I should think if Colt still has their Custom Shop, they should be able to refinish it to specification.
I don't think the question can it be refinished to his spec, the question is financially is it worth it. And the only opinion that matters on that is the op's
Contact CCR refinishing in TN. They did a S&W .38 for me that was in worse shape than yours years ago and it still has no rust today.

They don't make any snake guns anymore. Why is the python worth far more than the others? It was basically a custom gun that was hand built, not assembly line produced. That you could've bought them for less money a decade ago just means we all should have bought every one we could lay our hands on.
