Here are two less common styles from Great Britain! Actual postage additional:

First is an early U-1364A British telegraph insulator dating from the 1870s. These were made in two pieces with the inner skirt cemented in. It is marked VARLEY PATENT 8 -- designed for 8 gauge wire. This one is in nice condition with just a light wire rub and a few minor flakes. This one has the original pin cemented in -- I can cut the pin below the base if desired so the insulator will sit flat. $60

Next is a tough style to find -- U-1982 with two inner skirts! (treble shed style) -- marked on the crown BULLERS LTD -- excellent shape - $60

Or . . . take the pair for $100
