The Thistlewood Sowerby CD-ROM pattern book XI (1885) shows pattern 1088 in the following shapes with the same features of stipple frosting and raised flower motif to the sides, but sometimes the stippling is in panels (as the custard cups) and sometimes stippled overall (no panels); sometimes the top rims are plain, sometimes beaded, and sometimes reeded; all are shown with lozenges against the illustrations:
Page 5 butter dish no panels
Page 14 custards panels plain top rim
Page 57 covered sugar no panels reeded top rim
I also have a creamer/jug and a pedestal sugar bowl (photos below) in the same pattern (both with lozenge for 1 January 1875 – parcel 2, corresponding to RD 288210), neither of which seem to be illustrated in the 1885 catalogue.
Neither Thompson nor Cottle has a design description for RD 288210, but it must surely have been for the decoration rather than the shape.
Sowerby patterns 1074/1074½/1074¾ appear in pattern book XI (1885) always with stippled sides (sometimes in panels and sometimes not), with varying top rims or decoration, and mostly (though not always) with a lozenge.

See photo of the 1074 comport (as on page 19). This bears the lozenge for 22 April 1874 – Parcel 8 (corresponding to RD 281933). Presumably the other 1074 pieces have the same lozenge, and so would also appear to have been to a design registered in 1874.
Only the finger cups on page 31 have the raised flower motif to the sides. I wonder if these have simply been mis-labelled in the catalogue, and should perhaps have been shown as pattern 1088 also?
