Here's mine. My Pop gave it to me @ 1972 to bribe me into shaving off my beard.
So, I hacked it off for a couple of weeks and grew it back. He didn't care cuz he knew I'd never part with it and it would be cared for.
My holster is stamped 1918, made in Chemintz? Germany.
Nice looking rig.
The holster is one not often seen for a WW1 Luger holster. It of the so-called 'Police' type. The flap securing strap pulls up from the body of the holster, passes thru a loop and buttons to the flap.
(Artillery Luger holsters used almost this same idea/style of flap closure)
The standard German Army issue belt holster of WW1 (&2) had the steel buckle fastener on the body of the holster w/the short leather strap sewen to the flap.
Add,,
M.G.... Machine Gun,,
S.T. . Not really sure what it would be. 'S.' was usually a Medic or Medic Support type. I think it's also used to denote a Signal Corp type of operation too.
'T' usually a Supply Unit/Train/Column. Don't know if this goes along with the M.G. though
If any of that put together makes sense. There are so many different markings and variations, subtle differences in that even the height of the character means something different. Plus the different German State Armories decided on somewhat different meanings for some.
34.. could be 34th Regiment. That # is usually found in front of M.G. in the stamping.
12.. probably weapon # 12
All just a guess.
After late 1916, the Germans decided they didn't have to Unit mark the issued weapons anymore. But some were still done, probably for pride and old habits.
