Attached is a link showing a glass or crystal (has a nice ping) epergne which has a marked epns base. I am trying to identify the manufacturer. The makers mark is of a bee, fly or wasp with wings outstretched. In each wing on either side there is what looks like a "B". Does anyone know who owns this mark and when the epergne is likely to have been manufactured?

I have also put a shot of the entire epergne on the site.
