Hello dear friends. Thanks you very much for the detailed explanation!Qrt.S wrote:The guardein i.e assayer is either Jens Kahrs or his son Ditmer/Ditmar Kahrs, more likely the latter. He assayed in Bergen gullsmedaslaug in NORWAY together with his father Jens 1765-1781. After his father's death 1781 Ditmer change his guardein mark to just DK as from 1781-1788. He dies 21.5.1788.
The maker SWB is Steen Wirthmani Brygman, born in Alfstadhaug in Helgeland in 1717 or 1718. He became master in 6. of August 1748, He was alderman in the guild 1760-1762 and 1765-1766. He dies in Bergen 22. of March 1785. Your strainer is made between 22. of July 21. of August 1778 like AG2012 already mentioned.
