This might not help you Don, but maybe someone else may benafit from it along the same lines. I'm sure that there were many material changes after the "big one".
My 1950, 3604 has the original wiring harness and is in good condition and looks like this;
From the starter, across the upper firewall and into the ignition switch is cloth loom. From the light switch and through firewall the loom for stop light switch, regulator, generator, horn, and lights this is tape wrapped. The jumper across the core support from terminal block to terminal block for the head lights is tape wrapped. From the terminal blocks to the head lights is cloth loom. The loom that splits off to the gas gauge and all the way back to the tail lights is cloth loom.
