88 mm question

[Daarom]

I understand every abbreviation. Factory maker material waffenamt. But what does Du stand for? What do you think guys ?

[Teck 147]

Is it Du or Bü?

[Daarom]

For me .when i look good ,it is Du with umlaut 2 dots.

My guess and I googled it and couldn't find anything, would be the manufacturing city maybe? DÜ. = DÜSSELDORF (An educated guess)

[Daarom]

Aha Dusseldorf maybe .Thank you for your reply.But why camouflage the manufacturer with a code ATY but still show the location?

aty Maschinenfabrik fuer Massenverpackung, Luebeck-Schlutrup.Dusseldorf is in a completely different location
