I'm in the process of bringing a 42-1008 back to life, and I've had to replace almost all of the rubber insulated wire in it. Much of it just crumbled from being moved at all, some if you looked at it the wrong way it would crumble. Seems the yellow, red, and orange colored wire was the worst, the black and green ones were still relatively pliable after 75 years. Maybe whatever was used to pigment those particular colors is what made some of them become more brittle than others.
