You did indeed previously mention those things. Thank you. My thought was to add the web links to make it clear where they came from.
I have just been informed that the bowl was made by Bob Crooks, while the engraving was done by Julian Cole.
As for lettering on glass, I personally quite like it. The museum has a couple of bowls by Karlin Rushbrooke with quotes from poetry on them, sandblasted rather than engraved. He created quite interesting effects by overlapping the text round the bowl and using a fluid font.
