Silver German Beaker identification

[Arrski]

Hi guys!

Can you help me with identification of this silver beaker origin?

Looks like my picture didn't show. But here it is.

Hi,

Welcome to the Forum.

An image of of the marks is required.

The only other mark I have found is this. And there is also number 75 at the bottom of the cup.

Hello, this is not a maker's mark, but a former owner's or donor's monogram. Is it possible that the 75 is actually an incompletely struck 750 ? Regards, Bahner

I double checked, but it clearly look like 75. I wonder where I get this monogram indentified.
