Best thing to do is either go for broke and rip it all out, or gently pig tail what you have there with the same gauge wire. I do that with all old wiring so any further maintenance and repair does not yank on those wires.
I'm not advocating saving that wire. I'm only saying I could live with it.

I had the same experience with the same kind of stiff canvas covered wiring. On occasion the whole insulation crumpled away especially at the entry point into the wiring boxes. I slipped two layers of heat shrink tubing over the remaining insulation as far into the conduits as possible. This created new insulation right at the most critical point of entry and inside the wiring box for the lenght of the wires. It looked like the wiring inside the original metal conduits, being undisturbed, still did it's job.
