We had no way of getting the insulators at the time. However, they were eventually "liberated" from the pole and the entire lot came back home with me a couple days ago! I really appreciate adding something like this to my collection. These are both from the early 1900's. The Varley is incused "Bullers LTD London" and the Sinclair "Bullers Ltd London Patent". Both are almost perfectly mint. The soot will be staying on them. The crossarm had to be cleaned up a bit to remove the moss on it.
