This one offers a Gilbert American Flyer S Gauge Electronic Whistle Control Box, in the original box with original packaging insert. Cord on this one is pliable, and the internal vacuum tube came to the expected glow when I plugged the unit in. Also, the knob on this one is functional, and operates as expected. Piece is very clean as shown in the pictures.Please let me know if you have any questions, and thanks for looking! I'm always happy to combine shipping on multiple winning bids. Please keep an eye out for my other listings. I've recently started listing items from a collection, and am in the process of thinning it down a bit.
