Discuss Patina. Precisely - ethics of Patina.

[TNR]

This is a 12ga VH - 1 1/2 frame, 30" barrels. I purchased it at an estate auction about 10 years ago and, while it is not the prettiest, it is probably the most unaltered Parker or elsie I've bought. Chambers, chokes are original. Not a single screw is buggered. No pits. Just worn checkering, marks of use and a chip in the toe.

Even with its heavy use it is a seemingly well cared for working gun, and there is not a single alteration other than, and then only perhaps, a coat of lacquer applied to the stock a long time ago.

The barrel blueing is only worn on either side of the barrel - it's actually much better than my pictures allow. BUT, the receiver has attained a dark/speckled patina.

What makes a gun take on this "color" when others silver with use? Would you take bronze wool to it? Have a professional 'smith clean it?

I am just looking for thoughts and debate during this spring (cabin fever) - I don't plan on ever doing anything to this gun - other than killing a turkey with it in about 3 weeks.
