Need Help Identifying a Mark

Hi. I am new here and I hope someone can help.

I will try to take a photo of the mark I have a question about but it will be difficult as it is very small.

I do know it says either “B. Geyh” or “B. Geyn” within a rectangle and there are numbers for each corresponding piece by the mark.

It is a silver tea set.

Any ideas is appreciated.

Thank you.

I have attached a photo of the set. But can’t get a good shot of the mark.
