Thank you very much for your reply. It was purchased at an antique market in Brittany and I use it for late 18thC living history. Your reply is most appreciated.
I have a single chain French Chatelaine. I have identified one of the 3 marks on the website (between 1810 and 1838) but would be grateful for the marks at the top and bottom. http://www.dalecot.com/Chatelaine.htm (admin edit - remember to use the 'Preview' button) Kind regards Patti
