I have just purchased a soup ladle with similar markings as a photo on this web page. http://www.925-1000.com/platemarks.html
The silverplate marks are on the first photo on the bottom left hand side under Silverplate Marks. There is a slight difference on mine being the middle letter which is possibly a D or a M. Also there is a small 'c' enclosed in a diamond before the mark.
Can anyone give me any info on these marks please.
Thanks Jo
