WWII GI War Trophy: Walther PPK Question

First, thanks to everyone who provided a wealth of information to my questions re: the "Cogswell & Harrison" marked S&W revolver I purchased.

I now have a question on behalf of a friend. He inherited a Walther 7.65 caliber PPK that an uncle brought back from Europe at the end of WWII. The pistol has no Nazi markings, is blued, in good / very good condition, with the flap holster (has spare mag pouch, but no spare mag), and the US military form, signed by the commanding officer, authorizing the bearer to bring the pistol back to the states.

My friend has no other family members interested in this piece of history (I find that as bizarre and distressing as you undoubtedly do ...). He is seeking funds to purchase a more modern, full-sized 9mm pistol, and has no real use for the .32 Walther. So, he'd like to sell it, and has asked me to help determine a realistic asking price.

I checked some of the Internet sales & auction sites, but can't really get a "feel" for a reasonable value. I have personally seen only a handful of documented WWII-associated Walther PPs/PPKs for sale at some gun shows, but have no idea if the prices I noted there were reasonable (I highly doubt they were, based on other, more familiar wares at those tables).

If anyone can help, I figure it's the knowledgeable folks here. Any thoughts, ballpark figures or value ranges would be helpful.

Thanks in advance!

Schair, I researched my PPK awhile back and also found the prices to be all over the place. What I found was that the finish (military or commercial hi-polish), the markings (waffenapts and proof), manufacture year (by serial) and grip types are all critical in determining value. Military, police and Nazi party guns will go for high prices. In order to really get a value you will need to have good closeup photos of the PPK and the bringback paperwork. Also a description of condition noting any issues as well as pluses. Make a detailed list of serial number, markings (ex. crown over N and eagle stamps) and their location on the piece. This might be a piece that would sell best through a high end auction service in order to obtain the best return. Although these sell at a higher price than your average milsurps, there is a somewhat narrower market of buyers. Salt Flat

Thanks for the info, Salt Flat. I guess the devil is in the details. I like the old military pieces, but am certainly not an authority on them. I'll try to really examine the PPK closely, note all markings, grip details, etc., and chek around a bit more.

Appreciate the tip re: specific markings, etc.!
