A new to me "P Kasten", which is the box designed to hold 5 trommel magazines, a loader, and some 24 sixteen round boxes for the L. P 08 ; the "Artillery Luger".
This one must have quite a history, as we often say "if it could only talk".
Probably made about 1917 when the TM or "snail drum" was beginning to be used by the Germans. Perhaps it also served the Weimar police as a magazine for the Erma sub-machine gun.
Some how it survived two world wars, and years of use -probably as a tool box, until it was "found" in Poland by a forum member and imported to the US. When imported the "guts" had been stripped out and it was just an empty box as seen below. The interior was restored to the condition you see, using an original box as a pattern.
I have since added a couple TM's, loader, and reproduction WWI ammo boxes.
I have another TM, but as you can see- need two more to fill it up!
