»CDE, with halberds crossed; in a shield cartouche« = Carl Deffner, Esslingen.
Hello
This is the maker’s mark of
Carl Deffner, Esslingen am Neckar, Germany.
Carl Christian Ulrich Deffner (b. 4 Aug. 1789, d. 26 Oct. 1846), a young sales man took over 1815 a lacquers ware workshop of Rudy; and by his engagement, he build up a factory for metal ware, e.g. also be made in »Sheffield Plate«.
After his death, his two sons Carl and Wilhelm were two of the »driving axles« in Esslingen; well, there were more of course. Wilhelm installed in about 1860 [maybe earlier; date isn’t verified] in their factory their first Galvanic workshop.
The Carl Deffner factory never made items from silver alloy!
So the in your photo shown numeral »
12«
isn’t a sign for: Made from »12 Lot« silver alloy.
It’s a pity that you don’t show the marked item itself — it’s a »sugar box«? Please add a photo.
Their quality is of a very high standard level — apprentices of Deffner got every where a professional job. And almost metal ware factories in XIX century Württemberg Kingdom were founded by former Deffner employee.
Kind regards silverport
