Help needed with additional mark on a German (?) napkin ring

[jangerd]

Would anybody be able to help me identify this mark and/or the country of origin of this napkin ring? I believe the mark shows a "B" in front of a pattern that fills half of the emblem it is set in (click on the thumbnail and then enlarge the picture - the details can be seen very clearly). Thank you very much for your help!

i thinks it was made in switzerland - bern or basel about 1900 / 1905
