Arvin Industries was based out of Columbus, Indiana which is just east of Bloomington, where Indiana University is based out of.
they made great radios back in the day, in fact I have an Arvin made Coronado model 650B Farm Radio (battery only set) from 1938 and that radio is a great little performer as it picks up tons of stations at night with a 30' long piece of wire hooked up to it.
