Picked this one up last week. I think the handlebar, stem, grips and seat have been replaced, but the rest of it is original including the gigantic faceted reflector on the rear fender. 24" wheels and tires were OE on these bikes. From the Montgomery Ward catalog: "Frames, forks, handlebars, and truss rods made of light weight Duralium—the same aluminum alloy used in streamlined trains and airplanes." Should clean up nicely!
