Additional Unknown Mark

[robino032]

I have identified the manufacturer's mark on this as Bruckmann & Sohne but have been unsuccessful in finding out information on the mark on the very right- which appears to be a hexagon shape inside of a hexagon shape (but no letters). This is taken from a large set of what is likely 1930's silverware with monogram on handles, and brought into the US in the 1940's. Any help would be appreciated!!
