This cool insulator would fall under the no name AM TEL CO, EID in the guide. I would say that these no namers are probably more difficult to obtain than the AM TEL embossed pieces. You just don't see too many of these buggers around. Insulator is a good solid purple, crudely plunged in the threads with some threads missing, and in VVNM condition, it has a tiny dome scuff a WG lip sliver and one tiny fisheye. Displays perfect. Book is $40. My price....$34 delivered.
