Thanks Bernard. So 'British Make' is OK for Bagley after all. Sorry for confusing the issue ...
Steven â€” please do not apologise for expressing an opinion! And always remember that my views are just my opinions, and I have been known to get it wrong, more often than you may think!
Tony â€” thanks for resurrecting that topic, as there were some interesting points made there. I think it has been shown to be unsafe to attribute British Glass purely on the use of expressions such as "BRITISH MAKE", "BRITISH MADE" or "MADE IN ENGLAND" in relief inscriptions.
On the subject of the three glassworks' flower blocks being too similar for it to be a coincidence, I've checked the dates. Bagley was certainly making their 227 block in 1927, which is four years before Davidon's compressed air technique was patented in 1931. Therefore I believe that the "Sag" or "Droop" technique as described in Davidson's 1910 patent was used for all these blocks. See Stewart & Stewart for details.
I doubt whether Davidson would have been willing to supply moulds using their new compressed air technique, which may have been in an experimental stage in 1927. No reason, however, for them not to capitalise on outdated technology. We know that Davidson was quite happy to supply other glassworks such as Walsh and Monart/Liberty with their flower blocks and holders, why not the equipment to make them?
