Here's a very unique U-1778 boldly marked TE, separated by a unique arrow. These were most likely made special order from Buller Jobson Brothers in England for the Chile State Telegraph lines in the very early 1900s. Only a handfull of these have been recovered having been buried for many years. This example is in super condition with only the wire rub marks seen in the photo (2 small in the wire groove and teeny spots on the crown ridge). Dark Chocolate glaze.

This unique porcelain insulator with alternating upper and lower crown notches was probably designed to securely fix the tie wire without causing breakage to the insulator. Perhaps one day the patent will be discovered. This unique insulator was marked using a time consuming and expensive process involving the use of wax that was placed on the mold during firing, as it melted it's left with a very attractive marking. Arrows were often used on early (circa 1900) British made insulators to mark military telegraph lines. The bold marking could be identified from the ground for quick repairs to strategic lines. A variation of this style insulator was made by Hermsdorf (Germany) in 1903.
