My name is ***** ***** I would be happy to help with your pots, they sound interesting.
Can you very kindly attach a photo of them and of the bottoms (including the bottom of the one with no mark) and I'll appraise them for you and give you a value.
Many thanks and wait to hear
PS. Once you have the photos in your computer, it's a simple matter to attach them. Just click on the paperclip icon, located above the text box where you are typing to me. If there's no paperclip, click on the "Add files" tab.
If you get stuck go here for help.
