Here is a picture of the "guts": I guess this is a slightly newer example, since the frame is not of the "u" type?
Typically, what would be the correct light bulb for this unit? It's got a "430", but it doesn't work. I have tried a #1447 (from my American Flyer spares) and that works, but the globe looks too small for this much larger engine...
