sounds a good glass Carolyn - unfortunately, looking for names of Stuart patterns can be a very long task - there are so many cut designs from this factory - just have a look some time at the size of the Replacements.com catalogue for this factory.
I had forgotten is was Canada - thought it was Oz - but probably true to say that anything 'Lynn moulded', and it's a feature that occurs on a variety of glass items, would have been made way back in the second half of the C18 - not the nineteenth - and as far as I know appears to have been a peculiarly British style.
Doesn't mean you couldn't find one in your neck of the woods - glass is very good at travelling - but probably unlikely.
