Hi again, I'm back with another puzzle

It is so tantalisingly nearly ledgable, on the base of a beautiful lead crystal vase that had me thinking Orrefors before I even picked it up.
Anyway, hoping someone might recognise it and be able to point me in the right direction
Have attached two pics (with talcum) one indoor, one outdoor and this is really the crispest I can get with my point and click kodak
thanks as aways and looking forward to some further discussion, Mel
