That's a cool chuck, and I agree with you that it seems to be an early one that became sold over here as Bison brand. They were very good chucks, fairly close to Pratt-Burnerd in quality. I think they now source them from Asian makers. Sad.
As for the wiring, I assume you'll just replace all of them since you have to pull at least one. They are likely all a bit crispy on the insulation after all the years of sitting in oil and getting warm.
