Here is an original lot of American Flyer Standard (Wide) Gauge straight track. As you know, it is not all that common. These have the small rectangular looking slot on the ties and the American Flyer name in the small circle logo.
ERA: Pre World War 2
FOR: Standard Gauge/Wide Radius
VERIFIED AUTHENTIC AND ORIGINAL AMERICAN FLYER STANDARD GAUGE TRACK
CONDITION: With all track pins. This lot of track is oxidized, as most is. You will want to shine up or clean as it is dull. The ties show oxidation as does the track. There is no major rust or other serious damage. Note that the picture is a stock photo--your track will look something like that, but may not be exact.
