...the housing can usually be made respectable with a wire wheel.
get 2 or 3 "different" spray bombs of gold and one of silver.
alternately dust the motor housing with all four in no particular pattern so it has large sections of each shade blended and clear coat when finished.(gold and alum. are soft paints)
it won't look like the restored gold irridated ones but will look nice and close to original which was quite dull
splash the wires and back w/red oxide primer....
