Here is one of three pieces my dad picked up at a garage sale today. I wish he would learn I don't collect american glass lol. So they are being offered up so I can possibly by somethign that fits better into my collection I believe all three are the 310 ein there is just so many in the 126's man blew me away. Anyways back to the insulator piece is what I would call vnm just two small white pin prick areas email me for pictures. Again not sure on value of these pieces as compared to book so lets go 650.00 shipping in is middle of top and bottom price for the piece in the price guide.
