It appears you've chosen the wrong one of two Reg. Nos. (from the same day)

Not sure which author you've used to get info on this design and it's an irritating coincidence that on the 15th of February 1850 Sherwood Registered two designs under Parcel 8, as can be seen in Thompson and Slack, though neither author specifies to what design each refers. Thompson shows a reproduction of the Register page - which does often give a few words of text as to what an item is - but on this occasion we're denied even that, as can be seen in the lady's book.
In TNA pix I have from Kew, Rd. 67467 is a milk/cream jug (good illustration of a pre c. 1860 top down handle), and 67468 is your unlidded sugar - in fact there appears to have been a little license taken in the eventual design of the basin. The original factory drawing shows a substantial sized knop immediately under the bowl - it would be useful if you're able to add another photo, straight on, to see this feature - assuming it's there. Just one of those quirky and unfortunate situations that without access to the original factory drawings we'd be clueless which Rd. No. belonged to which design - when there are multiple designs within one date and one parcel No., then the lozenge system fails us, especially with obscure small houses like Sherwood. This doesn't happen with post lozenge Nos. where each design is allocated a separate Rd. No.
Later today I'll add Kew pix of both of Sherwood's Registrations for these items - unfortunately, I'm unable to add anything as to the history of George Sherwood.
