Municipal Police marking

[thunderdawg]

To all:
Having started at least this recent thread, let me add a little more confusion. As I mentioned at the beginning, the front of the grip frame is stamped "S. Hn. 184.". One of the two magazines has stamped on the back edge "S.H.184.". On its aluminum base are the four digits of the serial number and the number "2" below. Above the four digit number is stamped a 45 degree arc, concave forward (upward), with 7 radial lines pointing to the rear (downward). There is what looks like a number "6" below this mark.
The other magazine has no unit marking on it, but does have the serial number and "1" marked on the base. On the right side of the magazine, just above the base is stamped "STARK"

Ed, you asked in your reply why I thought my Luger was commercial vice military. Someone on another forum told me that the crown over N proofs on the left sides of the toggle and receiver (and no other proof marks) indicated commercial. The breech bolt has the two digit number, but no proof mark. You also asked about numbers on the top. The only numbers are the last two digits of the serial number: on the extractor, the forward toggle link (just to the rear of the script DWM), and the end of the rear toggle link.
If I can get good digital pix of the markings (gun and magazines), and how to post them, I will do so in a few days. Thanks again for all of your interest and comments.
