Mauser-Werke and Berliner-Karlsruher Industrie-Werke (BKIW), [BKIW was the successor to DWM (Deutsche Waffen und Munitionsfabriken)] had common ownership.  In 1930 the machinery, technicians and supplies were moved from Berlin-Wittenau to Oberndorf and BKIW's interest in the Parabellum ceased.  In 1934 Mauser obtained its first contract for 10,930 with the K-Date over the chamber.  For the collector there are four variations of the K-Date.

The inside of the gun is minty clean with no signs of deterioration for its age and exhibits that craftsmanship of the early Mauser production.  Unusual is the use of a DWM frame (129mm), that has not been reinforced in the rear or the 2mm extension to protect the rear main axel pin which Mauser was manufacturing into their Parabellums at the time.  Therefore this one came from the stock acquired from DWM.  Below you can see the Scriptic "S" proof on the firing pin retainer and proofed matching magazines.

As an example of the transition in proofing can be found on the firing pin retainer which has the Scriptic "S" proof.  Above Right are the two matching magazines with the B][90 proofs which continued into the 1935 models. Police Lugers were numbered numerically 1, 2, 3, for the extra magazines. The #1 was the primary magazine and was in the gun while the other magazine was in the holster and doesn't show a lot of wear.

Here are some close ups of the firing mechanism with the sear safety and the magazine safety complete and intact just as installed.  This Parabellum has a PVT, explained later, which as a Police Academy might have just used the gun in training and did not respond to the requirement to remove the magazine safety.

Serial number placement is in the military ("exposed") style.   The serial number appears on the front of the frame, on the side of the locking bolt, on the trigger, on the bottom of the barrel, the side plate,  the left side of the receiver, the safety bar, the sear bar, the rear connecting pin, and on the extractor.

The inside of the magazine well shows the very rare extension of the short lived magazine safety in a K-Date! Imagine first of the minimal amount of K-Date's dedicated to the Police, and then the number of Magazine Safety's installed less the number rendered inoperative.  This is a jewel.

This K-Date Police besides being very rare by itself has an INTACT magazine safety. Shown above with the spring loop and pressed through a drilled hole in the frame to the interior tab which is still intact and this was the method of disabling the safety after the Polizei Interior Ministry so ordered.

Magazine Safety:  The magazine safety consists of a "U" shaped leaf spring with two extensions, fitted into the left side of the frame under the grip. (Seen to the left with the hole drilled in the frame.)

One of the extensions fits into the front and lodges behind the trigger while the other end fits through the frame into the magazine well.  With the magazine in place the extension is pushed left and out of the path of the trigger. Removing the magazine allows the safety to move to the right so the bar moved behind the trigger and prevents it from being pulled.  This was patented by Carl Walther in October 1932.

This rig contains two matching magazines with the  Early B][90 and S][91 appearing and the 2nd marked "2" the police designation for the second magazine.  The loading tool is proofed with the early Ö][37 one of the rarer tool proofs collectors search for.

The Barrel is matched to the gun with the caliber 8.83mm stamped representing the distance of the lands.  The 9401 serial puts this K-Date  early in the 2nd variation of the K-Dates.  Additionally you have the early Mauser B][90 proof including the magazines.

Below: The small PVT is the marking of the  Polizeischul fur Technische und Verkur (Police School for Technology and Transport) marks of the Berlin Police Academy.  The name was changed in 1934 these marks are found stamped above the barrel proof Eagle. It is unknown if this is a proof by the Berlin facility or acceptance of the existing proof marks.

The side plate has the Gothic "S" and the sear stop is marked with the Scriptic "S" which illustrates that during the transition of the protocol for marking the Parabellum the changes were made with existing parts.

Above:  The four digit serial number that places this Luger into the designated Serial number placement is in the military ("exposed") style.   The serial number appears on the front of the frame, on the side of the locking bolt, on the trigger, on the bottom of the barrel, the side plate,  the left side of the receiver, the safety bar, the sear bar, the rear connecting pin, and on the extractor. Note the Scriptic "S" on the extractor yet we have the Gothic "S" on the S/42 code markings. This may have been a sample gun pulled from the various parts bins and not sequentially produced as the military K-Dates were.

At the  front is an E33 which was a very early Mauser Proof. The Sear Safety is marked on the bar that is pinned on the top of the rail and which fits over a slot in the side plate to provide access to a pin that drops into the sear when the side plate is removed.

SEAR SAFETY:  During the 1920's it was determined German authorities that one could remove the side plate with the gun loaded, thereby exposing the sear, and by then pressing on the sear discharge the gun. In this case you can see the sear safety probably fully installed at the original time of the first re-work.

This was the invention of Ludwig Schiwy, a gunsmith and the owner of F.W. Vandry & Company, Berlin. It consisted of a spring-steel bar on the top of the trigger plate which springs down into a recess in the sear bar, locking the mechanism, if the trigger plate was removed.

The holster is subtle and well stitched.  The internal loading tool pouch has a flap to hold down a loading tool.  The back of the holster bears the manufacturers cartouche and the 1934 date along with the "Star" of the police acceptance between the belt loops

The police holster distinguishes itself from the military holster by the strap and the stud obverse located to the military holster with the buckle and strap descending from the top flap. BELOW: The loading tool pouch is functional and the stitching for the cover is in very good condition.

The tool is proofed with the very early Ö][37 proof and is not serial numbered as standard police tools were marked.  Above Right: The toggle in full recoil reveals the serial #01 (last two digits of the guns serial number). In 1932 the Reichswehrministerium issued an order that the rear main axel pin be serial numbered to the gun.  You can also see a fine examples of the fire-blued pins.

In early 1930 production was begun by Mauser in Oberndorf with the transfer of  the tooling and equipment from BKIW (DWM) factory in Berlin to Mauser-Werke. The first order was for the Dutch in November 1930 and then the American Eagle orders for A. F. Stoeger.  From 1930 until 1934 Mauser assembled many thousands of Lugers from DWM parts and stocks, plus reworked other for the paramilitary groups and the police.  Mauser proof marks left a trail across many Lugers.
