I cut the Copper loops off the end thats easy to get too, using a angle grinder.
Then I pick out the loops.

Then I start bashing the Copper contacts & they break & fall out. They have bits of insulation/bakelite stuck to it, so its pick it off or give it the 'fire treatment'.

But mostly the wire is really stuck in there with Varnish, so I burn that off in a fire when I do all the other stuff I have saved up, that needed the fire treatment...
