great find David, congratulations

- agree it's a shame some of the painting suffers on these enamelled items.
You're right about the original date of first Registration for 'Stratford Rings' design.
According to Andy McConnell there were something like 600 enamelled designs introduced between 1928 and 1939, with Ludwig Kny being responsible for the mostly floral patterns until 1933 when Geoffrey Stuart provided the more fashionable Art Deco designs. McConnell suggests that most of these enamelled patterns were in fact added to Stratford Rings shapes................... anyway you only have another 599 to go

Date wise looks to be from somewhere between the late '20's and the late '30's, and always possible yours is one of the Kny designs, but that's just my opinion.
Although you don't give a size David, my thoughts are this is not a comport - do you think more likely a cocktail glass of some sort - which would fit in with the period ?? Of course, if it's nine inches across the top then you could be right
