World War II era PPK?

[nondescript]

A friend of mine asked me last night about a PPK his dad found among his grandfather's belongings years ago. I told him that I don't know much at all about old guns, but I can ask online about websites that might have information about WWII weapons. Google searching has only turned up online stores for vintage memorabilia and new parts for old guns.
So here is what he said he knows about it. His grandpa had mentioned a PPK that he had "from the war", the finish has turned somewhat plum colored, his dad has not found any trophy/capture papers, and the grip and "pinkie extension" on the magazine are green/tan camo. That last part seems kind of weird, but he says that his dad found it that way, and that his grandfather had told him the grip was on it when he got it.
My friend is trying to have his dad send him some decent pictures of it, but I figured that it doesn't hurt to ask if anyone knows some good websites for more information.
Any assistance would be greatly appreciated, because my curiosity is drivine me crazy.

It would seem that the "plum color" would indicate that it has been re-blued, with to high a temp. T he tan & green "Pinky" would indicate that it is not WWII That is, the mag may not be WWII, or that it is and has been painted or an after market thing.

The gun could be WWII, but reblued, and an after market mag inserted. Like you say, pictures would be great.

What is really needed here is an *exact* description of the slide markings and a serial number. This should end any speculation as to when the gun was made. Many later WW-2 Walthers had a "plum colored blue" because they were rushed through the process. An off-colored magazine base is also possible, but less likely. As the war progressed strange things happened.

Yeah, I've been telling him to go to his dad's house and get some good pics of gun, serial number and any and all markings on the gun. Apparently, there are two more small handguns of his grandfather's that he was wondering about, one of which he says has only serial numbers, no other markings. The thought of a PPK with camo grips has been stuck in my head, though. His dad only lives about an hour and a half away, I hope that he'll get some good pictures soon.
