CD 590 - FOREIGN AMBER GLASS INSULATOR - This great looking dark orange amber insulator is heavily embossed "A.G.M - PI - 3" ... for the Australian Glass Manufacturing Co. and is in excellent condition. I was told two interesting facts about this CD ... that this was the only glass top cable groove style insulator ever produced in Australia and that these particular insulators were only produced for one year - 1951. ( Please email me if any of the information I've posted about this insulator is not correct ). The price is $42.00 + $7.00 for Domestic Shipping or Free Deivery to the Mid-Ohio Insulator Show in Ohio next month. Personal Check - Money Order or PayPal OK. Please email if you have any questions. Thanks!
