This one offers a Gilbert American Flyer 561 Diesel Horn, with the original box, instruction sheet, and controller. Pictures do a good job of describing condition. What they can't show is what a strong sounding unit this one is - works great! 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 came into a collection and am in the process of thinning it down.
