To complete the Bob Scafe's collection. I have this Greek insulator, picked in Greece around 1980, by a friend. It is a U-1267. H= 114mm (41/2), D=78mm (3). Inside the circle a triangle and the letters Ar. Engraved over the dome, a square with the number 93 (Year 1893?). The thread contains some hemp. The wire is original. The glaze is very nice, white and glittering.
