Hi! Martin, Thanks for your valid info. I have spent a lot of time trying to obtain as much information as possible regarding this particular piece. I am lucky to have all four in excellent condition considering how fragile they are. Could you tell me if you have pieces similar to this design, especially paying attention to the pattern design on the base? I have most recently written to a company in order to obtain a valuation. I am hoping to hear from them some time this week. I would very much like to sell these on but with no idea about them, unfortunately I am stuck with them. I am sure they would look very nice in the right place and too desperate to find someone who is going to take pride in these such wonderful vintage pieces.
