This history was published in 1939. Unfortunately, for me, it is in German, but on page 137 there begins a year by year list of significant accomplishments. I am using my computer to try and create a chronology I can use.
I found the entry for 1893 interesting:
1893 July 28: Contract with the Minister of Colonies in the Hague on the supply of machinery and facilities for filling and closing tubes for the opium factory in Batavia.
- Juli: Vertrag mit dem Minister der Kolonien im Haag über die Lieferung von Maschinen und Einrichtungen zum Fiillen und Verschließen von Tuben für die Opiumfabrik in Batavia.
It was a different world back then! I can see where DWM would be well suited to make the machinery to produce and fill these tubes. Just another business opportunity. I suspect other ammunition manufacturers in Europe competed for this contract!
PS: I’ve finished this. It is about 7 pages long. No great insights, but interesting. If you’d like a pdf copy drop me an email and let me know. It is all machine translation.
