Interesting Erfurt 1918/1920 with Weimar unit marking

[DonVoigt]

I recently bought this Luger, primarily as it is marked to a Reichswehr unit- 12./J.R.5.41.

Keoki has helped with the interpretation of this marking and it represents the 12th Company of the 5th Infantry Regiment, weapon 41.

It gets more interesting from there though, the serial number is 8031r, placing it late in production in 1918 not long before the end of the war. Finish is worn, but barrel is nice and bright.

The pressures of late production are evident in this example, rougher finish, no inspection on the grip screws or magazine catch,no bevel on the upper edge of the right rail, many RC parts.

A real puzzle to me is that though the pistol is all matching, except for the over stamped toggle numbers, and TD lever; it has only the c/rc and c/(B proof on the right chamber, along with an early Nazi firing proof to the left of this marking and the same but smaller eagle on the apparently original Erfurt barrel, where an Imperial eagle would be expected.

The toggle is Erfurt marked, has a broken crown die, it looks like it was originally # "02" it was over stamped with "31" to match the frame and barrel and other small parts are also "31" but originally marked. The breech bolt is RC marked on the right, but also has the early Nazi type proof eagle on the left where the Imperial eagle would be expected.

The original striker has been upgraded to the "grooved" version and the rear toggle axle is numbered, indicating some repair or other work after
1932 when these features started to be used.

It also came with WWII vintage "capture" or "bring back" paper,
dated March 1946.
