Hi all
I am now stuck on this one and would be grateful for some help

.
The goblet is made from clear glass with a twang of blue/grey. The base has a slight outer lip which it sits on quite steadily with a very smooth indent in the centre.
On the base is the letters H G L (I think anyway), im never sure of which type but its either engraved or etched or diamond point ?? in a hand written style.
The base lip shows good dull wear so its not new.
It stands at 14.5cms tall, 7.5cms base diameter, 7.25cms rim diameter
So far all i can come up with is Heraut & Guignard who signed HG who had bought out Leveille in 1906 signitures HG and Le Rosey art glass and tableware (many thanks to Ivo's book Glass fact file). But I cant find any examples of there work or signatures.
Obviously i could be well off the mark with this and the glass is probably something completly different.
Any ideas
many thanks in advance
michelle
