Found on a pair of small buckles with London Lions Passant of the 1740 —1756 period.
Note the top and bottom indents to the punch, and the striking judder on the lower one
Probably a lost register mark of James Harmar.
Harmar’s only known recorded mark (Grimwade 1374) was entered as smallworker at Wharton Court, Holborn Bars in January 1761. This mark is totally different to the above and is seldom seen. David Schlosberg records only one pair of nips with this distinctive mark.
Heal gives a James HARMAR, Silversmith at Ship Yard, Temple Bar in 1747 so a lost register mark for him appears likely .
Harmar was still listed in PR1773 as a bucklemaker at Wharton Court .
There is a chance we are looking at his father of course!
We could also be looking at HI upside down !
Another possibility is John Hague.
On 7 August 1759 the London Evening Post reported "This Morning was married, by the Rev Mr Penn at St Anne's Aldersgate, Mr John Hague ,an eminent Bucklemaker in Noble Street, to Mrs Wooley of Ratcliff-Highway, an agreeable Widow Lady possessed of a fortune of Â£5000 and Â£100 a year ".
Although there is no evidence of his being a silversmith, the Noble Street address and his eminence by 1759 indicates that he may be a lost register silversmith. And his marrying a wealthy widow is in character for a silver bucklemaker !
