Does this car have circuit breakers. Ford used them (usually two, mounted on a CB board under the dash) well up into the 50s instead of fuses for lighting and main power distribution. If it has a main breaker and it has gone bad, it will have the symptoms that you have with exception to the starter and the horn relays since they are independent and unfused.

A short in one of the systems may have started this if it is a breaker but I've had breakers that just gave out for no apparent reason before.
