I have a ppk s#250850K, looks like satin nickle or silver finish. Brown plastic grips, two mags, one with a finger ext. of plastic that is same material and color as the grips. Both mags are marked Walther. Original 1941 marked german holster(black). Gun is 7.65 caliber. The blue book talks of a wartime production model called a Verchromt in 32 or 380, differentiated by a dull satin type finish. Proof markings are crown N on both slide/frame. Can anyone help with Mfg.date or possible collectors interest. The gun is in excellant condition. Thanks, J.D.
