| Documented in "Almost Complete
Guide to American Flyer Sets" by Robert Tufts No illustration or factory literature available - Consists of 5x9 Action Display plus 26122 2 level display. Probably similar to 28115 (pictured above) but unlike that display it appears to include the 5x9 action display used as base for 3rd and 4th levels. |
