sincere thanks for the enthusiastic response, and of course the additional information from Bernard

I agree, those pattern book designs are hard on the eye, and whilst better for being there than not, demand stamina when viewing. The design of the base star is refreshing to see after looking at so many simple radiating stars, obviously the mark of a innovative designer.
I think we'd all be hard pressed to be critical of a great piece like this - but I do have a gripe, and that concerns what I assume to be the slightly over-done fire polishing - something not too uncommon on a lot of run-of-the mill cut pieces from the mid C20, which takes away some of sharpness of cutting. My supposed C19 Irish/Scottish bowl posted in 'Glass' on 12th July has that sharp feeling which remains after cutting - perhaps fire polishing was a process that came later in the C20.
Good to see your comment that........."Fortunately there are several members who are becoming familiar with them, so any erroneous conclusion here is likely to be challenged."
As to my dying intestate, and this bowl going back to a boot sale or charity shop, I shall make sure that whatever happens, it goes to a good home

Food for thought, though, this question of what we do with our glass, ultimately, when the grim reaper calls. Sell it all quickly at the first sign of a sneeze - or donate it to a local museum - there's no one in my family with the slightest interest (they're all philistines). Perhaps this is a debate suitable for the cafe.
