There is very little problem reading the resistor values on the N/A Schematic, plus every part is listed by number on the parts list.
Philco is the one that started using the odd-at-the-time values of resistors, ie 47K instead of 50K, 2.2 K instead of 2K or 2.5K etc.
They claimed that some color codes were hard distinguish under the then-new Mercury Vapor lighting, being used in their plant.
