Here's a rare porcelain U-1336 insulator that was found on a disused telephone line that led out of the capital city in Colombia. The shape is not particularly unusual but the dome stamp is. [id= 199834649] This is an old seal from a porcelain factory that was stamped in green ink. There is a capital A that is visible in the center. Only 3 of these were found and one had a cursive "P" incused inside its inner skirt in addition to the stamp. I assumed for many years these were made by De Fuisseaux Freres of Baudour, Belgium as this profile for an insulator is nearly identical to the CD 450 glass insulator styles made by the glass insulator manufacturer Verlica Belgium. However, while doing some research I found records that indicated there was a second insulator manufacturer in Baudour, Belgium called Petrie & Cie. (Spelling may be incorrect. No further details known). Since this piece has been found with a "P" on the inner skirt I'm inclined to believe this indicates Petrie & Cie made it.

At any rate, if maker data is correct then this insulator could date back to as early as 1885. No chips or cracks. Only flaw is a weird very tiny dome marking that could be popped glaze air bubbles. I'm offering it for sale to the first email for only $85 plus postage. Thanks
