RD 334642 corresponds to Sowerby pattern 1423 vase or trough (page 8, pattern book IX of 1882) - as per Cottle.
RD 334643 is a somewhat of a problem in that it could correspond to one of three covered mustard pots shown on page 36 of pattern book XI, 1885). The shape of the finial on the lid and the wide top rim would seem to suggest pattern 1396, it is shown as from a registered design, and the pattern number is in the right 'ball park', but the sides flare upwards and the handle is a plain loop. The Sowerby pattern 1802 covered mustard (and its pattern 1798 'larger' version) has the 'correct' handle (with a small triangular aperture below the main loop) and straight sides, but the finial shape does not match, the top rim is narrow, it is not shown as from a registered design, and the pattern number is 'out of sequence'.
Does anyone have photos of actual examples of these patterns to show, please?
Fred.
