Need yer help! This needs a motor. The field coil tests, "open". Stamped on it is Synchron 610 1 RPM 143RA and the wheel train is 2 and 1/4 by 3 and 1/4 with a 1 and 3/8" handshaft Wondering if Timesavers 20066 would work. It's wheel train frame is much larger and would require remount mod for spacing. Also wondering the probability of hands fitting as I don't wanna go thru that nightmare. If hands don't fit, what's the odds I could transfer their motor to my train.
