The National Archives online registration summary gives the reference for the registration on 22 November 1880 as BT 43/63/358659 , and the registration description as:
Registered design number: 358659.
Proprietor: Pembrook and Dingley.
Address: Hall Street, Birmingham, Warwickshire.
Subject: For sugar [bowl] and marmalades.
Class 3: glass
I find it interesting that the glass bowl appears to be of some quality, with a polished pontil mark and nicely-engraved registration lozenge.
By the way, Pembrook & Dingley also registered the following design on August 31 1883:
Reference: BT 43/63/403109
Registered design number: 403109.
Proprietor: Pembrook and Dingley.
Address: Hall Street, Birmingham, Warwickshire.
Subject: For biscuit boxes, sugar [bowl], marmalades and inkstands.
Class 3: glass
I will add both the registrations to the Registered Design Lookup requests list in the hope of getting more details of the registration representation in due course.
http://www.silvercollection.it/SILVERPLATEHALLMARKSP.html gives Pembrook and Dingley’s electroplate mark as ( P D over & ) inside a trefoil, and their working dates as 1887-1898. Thesame source attributes the same mark as their sponsor’s mark on hallmarked silverware.
http://www.silvermakersmarks.co.uk/Makers/Birmingham-P.html , however, attributes the same sponsor’s mark to Pembrook & Dickins of Hall St., Birmingham.
