having looked again at the Gulliver book, the following might help to add more detail regarding the decoration - or equally create confusion:
shell ribbing seems to have been popular - to the extent that three companies at least........... Hodgetts, Richardson & Pargeter - T/Webb and Boulton & Mills, all appear to have Registered designs during the second half of the C19, which incorporated this form of decoration on both feet and handles - probably more commonly seen on feet. These small wheel cut stars are also typical of the period.
I'm not well up on these Victorian decorative styles, and there may also have been some plagiarism re shell ribbing, with the design having been used on the Continental as well. As mentioned, Stuart did use shell ribbing decoration (mostly on feet??), but Gulliver doesn't provide information as to whether or not this feature was included on any of the pieces from this factory's Registered designs - perhaps others might know the answer to that one.
Looking purely at Gulliver's hand drawn copies of the National Archive illustrations, my personal thoughts were that the ribbing on this piece might just look more similar to B. & M. rather that the other two, which look to have more ribs in their designs.
