VoPo-Luger marks

Juergen & Partick, I reject the Russian X theory, as some cleaver salesman thought he could pass these off as the Russian crossed Nagant rifles as seen on the M06 Russian contract lugers. I've only seen the "X" on a few E German reworked PO8s and feel that it indicates not require for military use, much the same as the "P" on Swiss lugers.
