To all collectors that own one or more Mauser K-date Luger(s).

Upon request of a growing number of Luger collectors I started this survey of the Mauser K-date German Military accepted Lugers, in order to obtain a further insight of the various sub variations within this intriguing group of Lugers.

General information:
Mauser obtained during 1934 a contract for the delivery of the P.08 Luger Pistol to the German Military Forces. This contract was established for eight years – ending October 1942. During 1934 and 1935 the Treaty of Versailles was secretly violated by stamping the chamber with a code ‘K’ for 1934, and a ‘G’ for 1935. As from 1936 the German authorities felt strong enough to quit this concealed marking, and from that moment the year of production was stamped upon the chamber.

Only about 10,930 K-date Lugers have been produced during the last months of 1934. During this short period Mauser used various methods of markings and proofing. In the beginning all parts bore scriptic ‘S’ inspection stamps, these changed step by step to a gothic ‘S’, and then gradually disappeared. The last 1,830 Lugers within the K-dates series are reported not to have any inspection stamps on parts.
In his ‘Third Reich Lugers’ on page 15 Jan C. Still has classified four sub variations, based on the appearance and the style of the inspection stamps, and the style of the ‘S’ in the S/42 code.

About 300 K-date pistols were reportedly procured by the German Navy, these bear an Eagle/M and an O (or N?) property number. Jan C. Still has classified these as the ‘Navy Variation’.

All pistols obtained the rust blue finish, strawed small parts, interior surfaces were polished bright after bluing.

The aim of this Survey.
Apart from the above described various inspection stamps, the pistols of the K-date series have also some other specific variations in their appearances.

1. - All have the thickened or ‘long’ rear frame, but in some cases the so called ‘Mauser Bump’ is found. (See below for pictures). It is interesting to find out if there is a pattern throughout the S/N’s.

2. - All barrels have a length of 4 Inches, and have also a sharp edged barrel band. In some cases however, this barrel band is longer, and the front sight is set back to match the rear side of the longer barrel band. (See below for pictures). Here also it is interesting to see if this was done at random, or that a pattern can be found.

3. - The Army Acceptance stamps on the left front side of the receiver are reportedly variations of the following: Ö|37, B|90, and S|91 (S|92?). The (mixed) use of these stamps has not yet been matched to the S/N’s.

4. - The bodies of the magazines are known to be made of nickel plated crimped sheet metal, the bottom is slant cut with an aluminum base secured by a pin through the rear of the base and the tube. Reportedly the early issued magazines had a marking on the spine of the body, near to the bottom. Also it is interesting to find out at what moment the proof marks on the bottoms changed from Ö|37 to B|90, and to S|91.

5. - The Navy issued pistols can be recognized by two markings: an engraved eagle above a letter ‘M’, and a property number after an ‘O’ or a ‘N’. When Sam Costanzo wrote his book, he reported six different styles of eagle/M engravings for the K-date series. (See below for pictures). It is interesting to find out if all these are still around 29 years later... Also the place on the pistol where these markings can be found is not yet fully known.

6. – Reportedly there were no official Police issued K-date Lugers. As we know now, the Police forces procured occasionally Army issued pistols at a later moment. It is interesting to find out if there are any K-dates around with a sear safety.

7. - Most K-dates have a indention, on both sides of the receiver, close at the spot where the barrel screws in. (See picture below).

We need a lot of information. So let’s make it easy to respond!
There a six questions. (For a Navy issued K-date there are nine). It is a long list, but I tried to set it up in a multiple choice pattern. You can present your K-date(S) properties in a fairly shorthand manner. This is an example:

1.SN 675a - 2.S91-S91 - 3.d - 4.b - 5.b - 6.675a/675a, spine 'H'- 7.d - 8.d - 9.O.1215

It might come handy if you select and print the list. You can take it with you to the pistol(s) and fill in what you find at ease. It surely helps to avoid mistakes in the shorthand string…

Of course, if you find something that is not listed as a possibility, please give as much details as possible to make me understand what you have there. I might even ask for a picture…

As soon as we have gathered enough data to establish a table with S/N’s and properties I will publish it here.

This survey is beneficial for all Luger Collectors. I greatly appreciate your help to get the K-date Lugers ‘under control’. You might send your data in this thread, or mail them directly to me thru the forum’s mail service.

Thank you for joining this survey!

Herbert,
Thank you for your quick reply! Please have a look at the acceptance stamps on K-date SN 3096 again. You report O/92 for the left most stamp, that is a unknown code...

Jan,
Thanks for your contribution.

Dave,
Also thanks - and yes; I would like to meet you again at Winston's ;)

Doc, I think a better guess would be B|90, or maybe another Ö|37. I don't think S|92 was used until the G-Date Production.

Frank, You are correct, of course. There is definitely a "90" there. The stamping is very light, I would vote for a "B".

To Taudelt,

Dave,
In your post above you gave the next data for K-date SN 7026:
(1) #7026 (2)B/90 S/91 (3) a (4) b (5) a (6) no K mag...
As the changes of 3.(appearance of scriptic/gothic inspection marks) until now seem to follow the pattern of issue, it might be that the 3.a for this SN is not correct.
Do you have the possibilty to examine this Luger again and doublecheck this?
Thanks!

Joop.... It belonged to a friend of a friend who I will see tomorrow at a show. I will ask him to check it out. I observed the gun in June of 2003 and perhaps the cheap wine I was drinking back then may have blurred my eyesight........

Also please note that #7763 does show the indent.

Will be back with you ASAP.........

Dave,

Tank your very much for your help!
In the listing I will put a sign only when a K-date does NOT have the indentation. They usually have. Also the first issues of the G-date as I observed this week.
Hey, I hope you never drink jug wines again... As will notice they can blurr your eyesight. These reds are only fit to marinate your meat in. As it is 17:00pm here, I just poured a first glass of a fine Kron merlot 2004 from Latia in Italy. I see much better now ;)
