17" Motorola B&W from '55 (not a good day)

Ah yes, a Moto with the infamous 'sex' logo on the front.

Good looking set, even by today's standards. Love those metal cabinets. It should clean up very nice!

If the Westinghouse uses a focus coil or magnetic focus unit, it's probably a 17BP4. If it doesn't, it could be a 17HP4. Westinghouse also used a 17YP4, which uses a different face curvature.

Correct ! The 17HP4 is shown in my old GE tube manual as Low Voltage Electrostatic focus... does not use a focus coil (or focus magnet assembly).
