This is one heavy insulator. Light aqua. These are getting very tough to find other than auctions where you end up paying a buyer's premium of 10-12%. This one has 4-5 quarter inch flat chips in the rear on the sharp outer base rim. It has a 3/8" BB chip on the rear lower wire ridge. On the dome top there is a quarter inch fisheye BB ding. There's a small stone in the glass just above and to the right of the word Patent. Larger bold embossing. Number 1 on the rear crown. Great looking old telegraph piece 130 years old.

First email gets this one for $275 shipped in the lower 48. Insurance extra. PayPal friends preferred. Money order okay, but will delay shipping until I cash it. Check is okay but will ship after it clears, unless we've done business before.
