I found these salt spoons, each marked with a 13 loth mark to the back of the bowl. I found one reference on the internet to a spoon of this identical design in the Solingen Klingenmusuem, but from a photo of a book entry (not sure which book), describing it I think as 16th century Renaissance, with Aphrodite/Venus terminal. Presumably these are 19th century copies? Does anyone have the full reference to the original spoon in the Museum. And a more accurate indication of age if possible? Or any other information would be greatly appreciated.
