On looking at the base again, I do not think that it actually states what we first thought and now feel that the piece is glass and not crystal.
On very close inspection and with the assistance of family members for extra eyes, it appears to read more like a signature as opposed to a company name.
To give possibly some extra oomph to the ID, the piece came from a private collector originally who also had Venini pieces, could this be a special that was made by Venini for its original owner or a one off special? I belive it to be a maker of note due to the amount of numbers etched into the base.
I have added two more images below that show the signature/company much better than the originals posted.
