I've looked through National Archive Representations books BT 42/62 and 63, which run from October 1870 to beginning of 1884 (the end of the lozenge period), and so far found nine Registrations for sticks from Sowerby. If you look at the page of sticks shown in factory pattern book XI (1885) - which is reproduced in Simon Cottle's booklet 'Sowerby Gateshead Glass' (produced for Tyne & Wear Museums (1986) - there are certainly more designs than I seem to be aware of from the Kew archives.
Not being too clever in the world of pressed glass I'm unsure whether this means that those I'm missing were Registered post 1884, or that simply Sowerby chose not to Register some of their candlesticks with the Board of Trade................. do we have any idea as to the likelihood or otherwise of Sowerby patterns that we know for certain were never Registered??
Answers on a postcard please to ................... Fred
Just my usual reminder, and know I'm always bleating on about the fact that I can obtain images of designs Registered after 1884 - but I do only hold pix of items from the lozenge years for immediate access - anything after that date means a visit to Kew.
Of course, if after having looked at the nine I'm about to show, people are aware of other Registered designs, for sticks, that I've missed - and you do have the Rd. Nos. - then please shout, and I'll do best to investigate and locate them.
Watermarking and resizing (twice) is a tedious and time consuming job, so have split these nine into two groups.............. five now, and the remainder later today. One of this first batch will run over to a separate post.
Quality of images varies from not too good to abysmal - these purple pencilled drawing are a nightmare to process, so apologies for lack of clarity but hope folk can see sufficient detail to know what the item is supposed to be.
P.S. just a reminder that if you're using Ray Slack's book, the first item - Rd. 307957 - is shown in the book incorrectly as 308957...... not a criticism of his work since we all make mistakes, but just in case folk think they can't find this one.
