I have spent weeks trying to figure out whom these makers marks are EC and I think a D surrounded by a dotted oval.. Just can’t seem to find anything with even the EC with the dotted oval.. or even the ll.l symbols no one knows what they mean. So this will stay a mystery.. We were going to sell them to someone whom would be interested. Not knowing who made them or how much to ask for them. I am clueless.. ,and will just keep them in the china cabinet for now.. So many people give me different prices that I’m afraid I might go to low or too high.. Thank you for all your help.
