I find the tag price difficult to read. If its $2995 the seller is high, and I mean high as in on drugs. If its $1995 the seller is still high, and if was "only" $995 the price would still be too high.
I have seen one other nickel P.38, in a shop about a decade ago, asking price was $900 and it has the original period correct holster. A consignment gun it sat there for several months. Finally went away, though I don't think anyone actually bought it.
What is pictured is, as 105kw pointed out a late war gun from one of the subcontract manufacturers.
It may have been nickel plated by a factory, some factory, sometime after WWII. but it wasn't done by the factory that made the gun. There were no "factory nickel plated P.38s" produced during WWII.
Next point "nazi party offical"...well, no, not hardly. Either way you take the statement, its not correct in historical terms, or general terms, unless the seller has the valid documentation to prove it is a rare exception to the general practice, which, I doubt. If the seller is not deliberately lying, then they are misinformed, or most likely just ignorant of what the Nazi markings
actually mean.
There was no Nazi Party "official" handgun. The German military did, but the Party did not. Nearly all Nazi uniforms include a pistol, but there was no "party standard" pistol.
Now, if they mean they think the gun belonged to a Nazi Party Official (a person), that is doubtful. P.38s were first line standard military pistols. Along with the P.08 (Luger) they went first and mostly to military personnel, and not just officers.
Party officials invariably wore other pistols, usually smaller ones. Walthers, Mausers, Sauers, and others and including pistols from captured nations were all used. Nazi Germany was always chronically short of pistols (due to nearly every Nazi uniform down to the mailman and dog catcher needing a pistol. They used about everything they got their hands on , and those guns were marked with Nazi Eagle & Swastika proof marks so today the uninformed might think those markings mean it was used by a Nazi Party official,
The Nazi WaA Pruf (WaffenAmt Pruf) is often only partial but if clearly stamped it is an Eagle and Swastika and an office number, and it is an acceptance stamp showing the gun passed inspection and is accepted for official service. That's all.
I'm not saying that specific P.38 could not have been worn by a Nazi party official but it would be very uncommon, and without valid historical documentation of WHO it came from (Gauleiter of Wittemberg.. etc.) then its just speculation and is only a story, to inflate the price.
The Nickel plating has destroyed its historical collector value. Its not a collector's piece, its a plain jane late war P.38 someone brought back from the war, or imported before 1968 and had nickel plated. Its not worth the asking price, not even close.
Not a presentation gun, either. I've seen several German presentation guns, including Nazi ones. and all of them were engraved, a little, or most usually a lot up to full coverage. Again, absent valid documentation, its just a BS story.
I do not accept the claim on the tag at face value, and anyone who buys that gun does so because they want a shiny P.38 more than they want the outrageous sum of money they are asking for it.
Not a good deal, in my opinion.
