I have a Sowerby Daisy block boat that I am assuming is the one on page 24 of Millers Popular glass of the 19th and 20th centuries, it is a pale green colour almost opalescent in parts. Sadly I don't have the stand.
The only difference I can see is that mine is 15.5 inches, not 14 inches. Did Sowerby do a bigger one?
I will try and take some better photos later, at the moment I only have one of it at the auction.
