We are lucky to have a shop in town that repairs alt. Gen. starters etc. Generator in my Model A ford blew up, took to that shop, I’m friends with the owner. He puts the armature on the growler and says it’s fubar. Then says wait a minute and we went to his parts room. He walks way in the back roots around for a bit then he pulls this thing out and blows a inch of dust off it and says I think this is it. Sure enough $65 later I was back on the road. I never laughed so hard as when he blew the dust off, thing must have been there for 50 years LOL
