The same phone man that gave me the big box of spool brackets told me he had some glass insulators out in his field too. This was just one of the neat pieces he had just lying in the dirt. Here it is after a good scrub! This is the odd embossing with "HEMINGRAY" on the back. Color is overall green with patches of aqua and some very nice olive swirls throughout. Oh darn ! .... two drips are cleanly sliced !
