well spotted Sid - certainly seems to be a good match, it appears on page 18 in section one. It's just occured to me Roy that like one or two other items which have recently been found missing from the lists of pressed glass registrations - this may have been overlooked by recorders such as Thompson and Slack etc. if it was fist registered wrongly as class 4, and not 3 for glass. You may well be reading the details correctly from the lozenge, but please tell us which class is shown at the top.
I can have a look in the Registers when next I visit Kew - just to see if it is in fact recorded in books.
