I can tell you that I have definitely had several '33-early '36 coils go bad on my cars, and the guys in our group who also own the same year early Ford's, and travel together, have also had issues with the original coils. The problem typically occures most often during heated conditions that expand internal coil windings, causing turn to turn wire shorting, and also primary to secondary coil wire shorting. When the coil internals cool, the shorting may temporarily stop/heal, only to occur again later during heated conditions.
