Continuing that line of thought .................................…
looking at page 112 in Cottle where he reproduces page 11 of Sowerby Pattern Book IX (1882) - the second item on the top line appears to be design 1569, and shows what looks like a two handled sugar basin, with three horizontal lines of banding - similar decoration to the piece here.
Sowerby pattern Nos. 1568, 1569 and 1582 (I think) - appear to be a small 'suite' of open sugar basins - and what links all three is the decoration in the form of multiple rows of horizontal banding, plus they all appear to have opposing short handles as shown on the piece here.
Turning back to Cottle's main text, he appears to list this three piece 'suite' of sugar basins as Rd. Nos. 362734/35/36 Sowerby Rd. Nos. - is it possible that factory item 1569 which could match the piece here - is either Rd. 362735 or 362736? All thee separate patterns were Registered on the same day.
