Here are two pairs of heavy fiddle pattern tongs (14 and 15cm) by Cape silversmith Frederik Waldek. Both with the same marks, in what has been called the Cape stub. It was believed the stub and associated fly press was imported by Lawrence Twentyman and used by a number of Cape silversmiths, but that Waldek probably took over Twentyman's concerns. Welz shows this as mark 165 and has his working dates as 1830 to 1877.

PS sorry if I am pushing posting rules here, but both have the same marks.
