I recently acquired a Lionel No. 248 Box Cab Electric Loco and I was surprised to see tan interesting reverse unit. It is different than the later "e-unit" but I also think it is different than the "pendulum" reverse units.
I have 2 other No. 248 locos, and neither is equipped with a reverse unit..,forward only operation.
Any information on this reverse unit would be appreciated. I've attached images and a video.
Thanks,
Steven King
