Just aquired this and i think i have a very scarce item because i cant find another set-up like it,so i am checking with the experts here. wondering on a scale of 1-10 how rare is it or how often do they show up 1 being all the time and 10 being never. I have done a little research so far and if i am wrong please correct me. Have a walther ppk eagle over n stamped on barrel and just below it,serial number puts it in 1940. no other proof marks which means it was private ownership an eagle over n means made after april of that year. I am confused on the serial number ending in k which i understand as for the military but no military proof marks and if military would not be in a box. Gun very very nice. Comes complete in orginal box with matching serial number on box. Has three practice dummy rounds in holder in the box, 2 have been struck one has not, extra mag, cleaning rod,alumin box with small bottle and some other fabric inside and the owners manual in german. i posted this earlier on the walther site but i see there are several knowlegeable guys here danny,jim, others
