Topic: Heavy glass tazza.

The stem is completely different. It's shorter and a different shape. Sturdier too, for the heavier top.
It there any evidence that yours might have been cut down, Keith? If it had been done a long time ago, as a repair/rescue endeavour, the work would have been fairly crude. Not up to the repair standards that can be achieved nowadays. Repairs were carried out - but using techniques such as drilling delicate holes in the glass and attaching metal staples - labour intensive but very crude.

It was just a quick thought based on the cut foot, airtrap stem, and frosted top, as OP didn't mention having already considered Molineaux and Webb.

I'll try and dig out the Victorian glass books.

Still can't decide with this one
