Some dateable Sowerby pattern numbers smaller than pattern number 1074:
Sowerby pattern 1031; RD 297042 of 17 December 1875 – Parcel 16.
Paul has already posted the design representation of RD 297042 a as reply #3 at
http://www.glassmessages.com/index.php/topic,54129.0.htmlshowing it to be a sweetmeat with ‘rope handles’ (shown at the bottom of page 44 of pattern book XI (1885).
(Oddly, the suite of ‘rope-handled’ pieces corresponding to the RD 297041, also registered on 17 December 1875 – Parcel 16, would seem to correspond to pattern number 1129, so pattern 1031 is way out of chronological number order).
Sowerby pattern 1032; RD 260404 or 260405 (not sure which) of 12 February 1872 – Parcel 6.
Thompson shows a representation drawing on page 30. An assortment of pieces in the same pattern appear on pages 3, 14, 17 and 25 of pattern book XI (1885).
Sowerby pattern 1035; RD 260802 of 29 February 1872 – Parcel 5.
I have a sugar basin bearing the lozenge, and a similar sugar basin shown with cover & underplate is shown on page 57 of Soweby pattern book XI (1885). Thompson gives the registration description as for a butter dish, and butter dishes in pattern number 1035 are shown on pages 4 and 11 of pattern book XI (1885).
Sowerby pattern L1042; RD 267742 of 7 November 1872 – parcel 7. Appears as a sugar on page 7 of pattern book XI (1885).
Sowerby pattern 1054; RD 274743 of 31 July 1873 – Parcel 5.
Discussed (initially as an unusual 3-tier cake stand) on the GMB at
http://www.glassmessages.com/index.php/topic,52868.msg300375.html#msg300375Sowerby’s earliest registered designs were a parcel registered on 2 February 1872 – parcel 1. They correspond to RDs 260183 to 261186, and Thomson describes them as covered dish, decanters and bowl (though doesn’t illustrate them). If Paul has the design numbers for this parcel and is willing to post them, then I may able to match some or all of them to Sowerby pattern numbers.
