Dutch is correct. I have a number of “UN” (Uttendoerffer Nürnberg) from WWI that are the normal German WWI Army format like the WWI Spandau boxes illustrated in some of my recent post on Munitionsanstalts http://iaaforum.org/forum3/viewtopic.php?f=8&t=13732.
This box has an almost commercial look to it, and does not comply with the requirements for an Army label. Perhaps it was for the German Navy??? It uses the “08” instead of “04” but the Navy container Fede illustrated in a previous thread is clearly Navy, and the label is dated 1918 and describes the ammo as “08” so sometime between late 1914 and late 1918 the German Navy began referring to 9mm Pb ammo as “08”. My wild guess is that this UN box was procured by or for the German Navy—perhaps…
I posted it to see if anyone had any other ideas.
Interested in what you think.
Thanks for the comments so far.
