The Electra name was used for many years. Avery Fisher used it as one of his first models when he was selling them under the Philharmonic name in 1940. The first two models were the Linear Standard and the Electra, both had TRF tuners at first made for the Manhattan market. (WQXR was broadcasting wide band AM classical music in those days). The Electra name seems to have survived into the mid 60's at least.
The one you described sounds like a 1959 or 60 early stereo model. The 610 with the 30 amplifier came in both separate cabinets in 1959 and were in a single cabinet in 1960.
