Big thanks to Bernard Cavalot for taking the time to examine this gondola at the Cambridge Glass Fair.
Due to the style of registration font, the mouldmaking and production values, Bernard felt it was reasonably safe to assume the gondola was manufactured by Greener. For myself, checking the registration font with another Greener piece owned by Philip Housden was interesting (never thought of checking fonts before!) and lead me to concur with Bernard thoughts.
There's always room for discussion though, and any other information would be interesting.
Many thanks to all who have taken part in the Great Gondola Hunt
, it's been an informative and educational journey for me.
