Re: walther ppk
Hi uncleger......welcome to TFF.
Without seeing your pistol.....it appears that what you have is a wartime production PPK that's known as a "Crown N - Eagle C" that was manufactured for the Nazi Police. The Blue Book values this PPK at:
90% - $600
80% - $500
Add 25% for high polish finish.
The extra mags, belt, & holster would add extra value, but I'm not sure how much. If they're original issue gear, perhaps as much as $100-150.
