I have started on an attempt at restoring a Harold Flory "St. Michael" electric speed boat. At least I think that is what it is. The hull and deck are aluminium and the colours are correct for this. Unlike the HF "Swift" that I have the joint between the hull and deck is all turned over and pressed or crimped, so I cannot remove the deck without surgery. There is very serious corrosion to the inside structures (motor mount and battery holder) which looks as though it has seen some salt water service. All that remains of the motor is a magnetic rotor on one end of the prop shaft, and the prop shaft seems to have a "crank" that may have been part of some sort of rotating contact. Can anyone help me with details please? Thanks for looking, John.
