Hi
A charity shop find, I thought it looked a bit different with its metalwork
I’m not sure whether it’s lead glass or not.
There are striations, small bubbles and impurities in the glass - there’s also a patchwork of iridescence.
Its inside base is raised.
The wheel cut vertical mitres have been polished.
There seems to be very little base wear, which probably means that it’s relatively modern - of course it could have
spent time in a tantalus

Its metal ( non-ferrous )collar and stopper have been lathe turned as opposed to stamped - you can unscrew the
top of the stopper from its peg.
I’ve no idea what metal has been used, could be an alloy that’s been plated with something—of course it could be
solid unmarked silver

It’s 21cm ( 9”) high.
Any help in identifying it greatly appreciated—thanks for looking.
Scott
