This piece I just acquired in a collection and not sure of the exact U # but its in mint shape and has a nice olive color glaze even up into the pin hole. From what I could find out this is a $10.00 - $15.00 insulator as I don't no my porcelain much so if anyone wants it lets say $12.00 U.S. + shipping. I accept PayPal using family friends gift mode. First email as usual. Thanks.
