For sale i have a real nice Montreal Telegraph Co. insulator in Blue Aqua EIN [020]. It has lots of nice milk swirling around and a nice bubble up front. Its almost threaded to the base and the thickness of the glass makes it a heavy insulator. It looks mint but lets say vvnm to be safe. Asking $125.00 U.S. + shipping. PayPal accepted in family friends mode and also checks.
