Some of you know I have been chasing this topic for over a decade and made almost no progress. Below is a question I sent to the ECRA Cartridge Researcher quite some time ago. No breakthroughs resulted, but it does lay out some of the aspects the issue. The basic problem is that we don’t have specific dates to relate to box codes.
Question on DWM Codes.pdf (175.0 KB)
Recently, based on something a friend sent me, I realized that there may be a way to group the box codes by production year or something close to the production year. I had not thought about it before because it involved DWM hunting cartridges, something I know almost nothing about. From 1925 to 1939 the cases of these rounds had a date code identifying when they were made which began with VV for 1925 and ends with GG in 1939.
Fortunately I had some information from another friend that provided a starting point. He had provided over 25 examples of boxes in various calibers and the associated box load code. When I arranged the case date codes by year and entered the box codes, I got the following:
code Year Box Codes
GG 1939 WE213 WE973 WU104
JJ 1937 071ALV WU496 WU230
KK 1936 WE082 WU083 WU270
LL 1935 WT994 WU456
MM 1934 290AR
NN 1933 034AEV
OO 1932 390ARV WU711
PP 1931 129ALV
RR 1929 395P 995P WU916
SS 1928 783S
UU 1926 395P
VV 1925 V974
This helped some since the ###Ltr codes like 395P sorted to the years before 1930. The other two code formats ###A Ltr Ltr or W Ltr### were mixed after 1930. The fact that there are were two DWM ammunition companies during this period, Karlsruher and Berlin may explain the two formats, or perhaps not.In addition, the Lubeck factory was established in 1935. Most commercial style DWM boxes I have encountered specifically identify the factory as Berlin Borsigwalde or Karlsruher. Unfortunately the source of the table above does not identify the factory on the box.
What is needed is a lot more information on these boxes with dated headstamps.
If you have a box with a dated DWM headstamp, please provide the following information:
Caliber, Headstamp including the date code, Box code, Factory identified on the box, is box marked NICORRO? Yes or No, any other comments you would like. For example:
9,3x74R JDWMJ/9,3x74R/474A/ 071ALV BD No Plus a comment
Factories are probably one of the following based on box label:
KD1 = Deutsche Waffen-und Munitionsfabriken Karlsruhe-pre 1923
BK = Berlin-Karlsruher Industrie-Werk A-G, Karlsruhe-1922 to June 1936
BD = Berlin-Karlsruher Industrie-Werk A-G, Karlsruhe vormals DWM-June, 1933 to June 1936
KD2 = Deutsche Waffen-und Munjitionsfabriken A-G Werk Karlsruhe i, Baden-post June 1936
DB = Berlin Borsigwalde
DL = Lubeck
NF = No Factory Shown
All help will be greatly appreciated. Sorting out the relationship on these boxes of dated hunting cartridges will not solve all the questions on DWM ammunition from this period, but it will perhaps give us the starting point to solve the rest of the riddle sometime in the future.
