An original American Flyer 5318 engine offered here with no reserve. Overall length is approximately 13" and all metal. I am unable to test it, so I do not know if it runs, but I am certain all the components are present. One issue of note is the top rear portion of the engine has a dark reddish paint color - I am not sure if this is original paint or if someone added the paint. Any questions or additional photos, do not hesitate to email me.
