Hi, Does anyone know where I can get a user/installation manual for a Westinghouse HI-Torque DC motor speed control, style 388P273, Serial RS, input:115v, 50/60cps, 1 phase. Output: 3/4 HP, 9amp max? This is an older unit (I'm guessing 70's?) but it is unused, just missing the manual, and it would be a shame to scrap it for lack of a manual. Thanks, in advance, for any helpful thoughts anyone may have.
