I need your help to identify the hallmark of a small silver MAN Munich bowl

[Donjuan]

Hello,
I have purchased this beautiful little bowl and would like to know who made it and how old it is.
Thanks in advance for your help.

I'm not sure if it has to do with it but MAN is a well-known bus factory in Munich.
