Picked up this motor along with two dozen others at an auction. I recognize all of them as Marx except this one. It doesn't look like any Lionel I've ever seen, and usually Lionel has their name on everything they've produced. American Flyer maybe? It doesn't run, but the lever on top chatters up and down when power is applied. I have no idea what the purpose of that is.
Any help or clues will be greatly appreciated. Thanks.
