Can say categorically that there aren't any designs (in glass) for biscuit barrels in the first volume of the National Archive Board of Trade Registrations. This first volume, of the diamond/lozenge registrations, covers Nos. 1461 to 84598 for the period 01.09.1842 to 06.04.1852.
Etched glass during the 1840 period seems almost non-existant, and the design of this barrel appears in general more advanced when compared to other pieces in that early period.
Attached are a couple of pix showing details of - coincidentally a biscuit barrel - Registration 237158 dated 15.12.1869 for Lloyd & Sommerfield.
Whether there should be a lid I can't say.
The date of Registration of the ebay biscuit barrel remains unclear - and it would seem safe to say that, based on the available details of the lozenge plus the form of decoration - and using the Board of Trade data at Kew - that at present it's not possible to confirm the quoted date of 1843.
