Hi, I am on the hunt for a vintage Kingsley foil machine, M-50 or similar. Has anyone ever had to do tune ups or repairs on these machines? Is it possible to do basic things like replace the electrical cord, clean the dials, etc. My husband builds cars and has *all* the tools, so I'm sure he could handle it. I'm more concerned with taking things apart only to have them disintegrate, and similar issues with vintage equipment. Taking advice! Also, if you have one you'd like to part with, let me know!
