DM 28 is the loading - here a training round

Hi Tony,
its the same DM number on your case - the NWM is Nederlandse Wapen & Munitionsfabrik ( probably not proper Dutch spelling ).
This type of Lotnumber give nothing without the refrence from the factory or the ordering organization - to my knowledge.
A friend of mine is making watches. I have attached some pics of his trial watch.

This is not a sales pitch or advertisment but should you be interested...

DM stands for Deutsches Modell or as previously explaned/translated as German Model.
NWM stands for Nederlandse Wapen- en Munitiefabriek `De Kruithoorn` (the Netherlands). NWM is closed for several years already.

Does anyone else make the DM1001? SO far we have Germany and the Netherlands. I am assuming there must be other countries as well?

Great Britain make the DM1001 also.

Yes, BAE Systems Royal Ordnance division did indeed make 27×145B DM28 TP ammo for the Mauser 27 mm BK-27 (Bordkanone) revolver cannon at one time.

Not sure if they still do, though BAE mention Glascoed being able to make medium calibre ammo in one of the documents I have.
