thanks Kevin - with confirmation of the Rd. No. correctly reading 756950, this now revises the date of Registration to c. 31.07.1930 - give or take a day ............. just thought it worth mentioning this in case anyone was charging off to Kew to look at the original factory drawing.

The reason as to why this Registration doesn't appear in The Glass Association Blue Book list of Nos., for those items post Jenny Thompson, is not obvious, but might be due to the original application to the Board of Trade being allocated as CLASS IV, as happens occasionally. It would appear I've not seen this item in The National Archives, so will have a look when I next visit, but if I have posted previously, and forgotten, please someone shout.
