Nope, but I wish I did!!
I saw one at a gun show a couple of years back, but the guy wanted way to much for it. It was a P38K in the original box with papers!! Imported by Interarms. That's the only one I have ever seen up close or otherwise!! They were not popular to begin with!! When it failed to interest the Deutschen politzi, Walther quietly dropped it in favor of the then new P5!!
