Vendor components usually have plastic insulation. Philco parts and chassis wiring is usually cloth covered wire. Manufacturing Engineering called out the colors and sizes according to Philco practices.
Production wiring was cut and tinned weeks in advance by machine and placed on the line at the position where it was to be used. No one would have wasted time separating wires hoping to find some unused lengths for use on another product. Even tubes and parts that dropped on the floor were not salvaged. They were continuously swept up and discarded.
At the end of a production run, unused material was discarded by the ton.
