Hello Nigel,
I thank you for your answer.
Conrad Hölling, 1651-1720, from Hannover Neustadt was goldsmith of the court of the Electorate of Brunswick-Lüneburg (informally the Electorate of Hanover) and also goldsmith of the royal british court (Scheffler, p.753).
The date letter A in Hannover Neustadt was used 1725; after his death. But probably he died a little later, because untit 1726/27 he worked together with the cort jeweler Lewin Dedeke from Celle.
Rosenberg mentioned the crowned "DD" and "D" mark as unknown marks about 1700.
Interestingly both marks seems to be only in combination with hanoverian court jewellers (Conrad Hölling with crowned D and DD and Hermann Sander with crowned DD) and on objects from silver chamber of the Duke of Cumberland.
Maybe in this context is to find the answer.
In consideration of the fact, that Conrad Hölling was also goldsmith of the royal british court, I would be interested, if there ist hanoverian silver from this early period of the House of Hanover also to find in England?
Kind regards,
Ringo
