Hello and welcome! My name is Doris.I have been an antiques collector, dealer and appraiser for over 56 years.I will be pleased to help you.
Please send me a photo of the CL Duflos?
You may need to use the macro function (flower icon) of your camera to get a good clear photo of the marks.
To send photos you may use the "attach" or "add" link or "paper clip" you see on your reply page.
