Part 5
The toggle train actually appears to be a complete replacement. The rear link is stamped with a Simson Eagle/6 where one would expect to find an Erfurt Inspector stamp. The front link is, very crudely and with different number stamps, numbered to this gun.
The breechblock is numbered to the gun, again crudely, and has neither inspection stamp nor power proof--indication of replacement. Not pictured, the firing pin has its original number 'X'ed out and 57 numbered above it--the crudest renumber of the lot.
The breechblock connecting pin is numbered 005, indicating to me an oversized replacement part. Rear toggle pins are known to have oversize stamps on them, but I have not been aware of front pins so numbered until now. It doesn't solve whatever fitting problem this gun has, the pin is so wobbly in the front toggle that I'm not sure that I'd want to shoot this Luger.
The rear toggle pin is numbered, appearing to overstamp another number.
The sear bar is stamped with an eagle over HZAJt18. This is the marking of a Heeres Zeugamt, an Army repair depot. A search of Jan Still's Forum yields a number of discussions on the topic, and several Lugers whose sear bars bear this stamp. Although there is some speculation about where these depots were and how they worked, much research is yet to be done before it is possible to assign a date to the Jt depot--if it is, indeed, Jt. At this stage one can only wonder what vagaries sent this Luger from its Imperial origins through Simson's rework system, into a Heeres Zeugamt depot, finally to end up in the H.P. Police organization. Very often these Lugers speak, but such eloquence is beyond this one at the moment.
The grips are numbered to the pistol but have no Imperial inspection stamps, indicating that they are rework replacements.
This Luger shares some of the recognized charcteristics of H.P. Police Lugers but remarkabley, not all. The right receiver is unit marked, in the same tiny, distinctive font, and the front grip strap is marked as well, in the H.P. designation which is so unlike the Prussian HP. designation. However, if you look at the overall pictures of this gun, you will see that it still has its stock lug.
