CD 126.3 - [010] --- Here's a real nice insulator that's heavily embossed - " PATENT DEC 19. 1871" on the dome and "A.U." on the front side of the base. VNM condition . Please email if you would like additional photo's. Please Note - What looks like it could be a crack on the base is not - just a light surface scratch. And what looks like white junk in the glass by the wire ridge is a good sized closed bubble with the light reflecting of it. The color show in in the photo is accurate. --- $65.00 plus $7.00 for Prioity Shipping. Will consider trading this piece for Foreign or Domestic insulators. PayPal - Money Order or Personal Check OK.
