 Time to let go of my American Flyer stuff! I tested this with a multimeter, and both settings work as they should.

No damage to metal case, no visible external damage to wiring. But since it's over 60 years old, I'm selling it "as is".

A few more American Flyer items coming to my ebay page as I clean them up and test them.

Thanks for looking!
