1970's Commercial Luger

Saw one for sale yesterday NIB with two mags. Incidentally, the original mags are black plastic bottoms. Anyway, I see at least one at every show I go to, and many are priced high. This one was asking $900, but would have gone for $750. However, on the rare occasion when one actually does change hands, it usually sells for $600 or less. I don't give this variation any serious attention. At those prices I can get a decent military shooter.
