2 Parkers

[Bindlestiff]

Yes, case color is the result of the heat process used to harden metal. It is easy to remove case color just through normal use of the gun. That is why its a sought after attribute when purchasing a Parker, so few Parkers have original case color today because Parkers were enjoyed in the game fields and shooting ranges and the case color was worn off.

If it has a lot of case color, look for a gunsmith that not only fixes Parkers but one that is also knowledgeable in restoration too. "Maybe" a good restoration man knows some secret that can bring it back to it original glory; but I am just guessing as this is way outside my knowledge base. It can't hurt to ask even if it can't be done, one never knows maybe it can? It also may be cost more than it would be worth.
