I have a cousin that worked the AE / GTE territory here in Durham, NC "back in the day".
I have a ton of 80's, even the cheap 70's versions.
He has an ivory bakelite 40, and a few 90's.
I've got an aqua 1964 80 with metal plungers; It was my great-grandfather's.
I remember I went to this estate sale, and paid $18 for a 12 button starlite. I later found one for free at a local thrift store a few days later...It had an extra-long-cord.
My cousin said they charged a ton for a long cord back in the day, like $30 or something.
" The long cord was a phone man's best friend."
