It would appear that the partnership of Daniel Hockley and Thomas Bosworth was not a long one.
I have a buckle with what appears to be Hockley's January 1810 sole mark with a date letter for 1816/17, the mark presumably being re-used after Boswell's departure.
Daniel Hockley then appears have entered into a partnership with William Snooke Hall, a fact not recorded by Grimwade .
