Here's a rare Green Jade Milk glass bushing. I believe I got this 6-10 years ago. Measures 2 3/8" wide x 7/8" deep. I've seen these in porcelain before but this is the first one I've seen in glass!! For a side view [id=579151817]. I've seen porcelain examples used on radio antenna bases. First email gets this unusual insulator for the reduced price of only $150 plus 8.00 postage. Thanks!
