Reading through the whole of the Wireless World article referenced by WD40 shows a considerable effort must have gone into what would have been a niche market at the time.

Much larger cabinets than the 3030, similar elliptical speaker with the addition of an electrostatic tweeter with a separate amplifier - an early example of an active crossover.

Looks to be the TR50 deck running at 7.5 ips half track (.110) stereo. Response to 16Khz - seems optimistic for 1956.

The cost would have put it beyond most people in 1956.
