Good Lord! This one's a heady insulator! Typical AM TEL CO toll that has a massive 1 1/4" of domeglass. You just never see this kind of domeglass in the toll type insulators cept once in a blue moon. I guess AM TEL was VERY generous with the glass on this pour. As you can see, this is quite a crude insulator! Only damage on this one is a few tiny fleebites and on the rear base, there is an almost invisible ghost fan bruise stemming from a small edge impact to the base. Displays mint. No dome numbers. First mail to me... $30 + actual shipping. Sold to the first person who looked!
