If you're the 121 collector, this should be a choice, must have piece to add to your collection. This insulator is your standard aqua but buddy does this one have a huge head! Almost all your AM TEL CO's have very little dome to them, this one has a monsterously generous 1 1/4" domeglass on top! The roof of the pinhole stops in the middle of the UWG lip. Insulator condition is VVNM, it has a few small pin pricks scattered about the dome, a very small sliver to the WG lip(seen in pic)and a couple base nibbles. Insulator displays about perfect! More pix available upon req. $24 delivered to your door.
