Hi Juke,
The term 'Unregistered Mark', so often used for unidentified mark of this period, is a misnomer, the mark would definitely have been registered. The term appears to have become popular since Arthur Grimwade first published his great work, and put the marks that he found on examples, but we not recorded in the registers at the London Assay Office, into a separate chapter entitled 'Unregistered Marks'.
The reason that the marks were not available to Grimwade, was the loss of the Largeworker's register (1758-1773), that would have contained the entries of many silversmiths such as Richard Gardner. Grimwade speculated that the register appears to have been missing since at least 1863, but research by John Culme in 2000 makes it likely that it was lost during a fire that occurred at the temporary London Assay Office on the 29th July 1830, during the construction of the present-day Goldsmiths' Hall.
