Postwar Lionel FULL OVAL 2383 Santa Fe F3 diesel locomotive units in master carton. These units are gorgeous but do show slightly more than a test run. They are exceptionally nice and clean with no battery damage and no screw cracks, C8-9 in a master carton that has writing on one end, brick inner boxes that are each sealed on one end, Lionel wrap, original instruction sheet and warranty card. The full ovals are a bit of a mystery as they show up on the 6th page of the 1964 catalog but they show up nowhere in the 1963 or 1964 catalogs. For those of you who are wondering what the full oval is, please look at the nose decals and see that the black line oval is not broken at all. According to John Schmid, there were only 60 sets of these shipped by Lionel in master cartons, there were others that would have been included in passenger sets. We do not know the exact number of these that were made but they are not exactly readily available out there and many people do not even know about them. The master carton is not the one that these would have been shipped in, to the best of our knowledge, Lionel also made generic master cartons later on for repair jobs, etc and this is one of those cartons. The correct master carton would actually be dated 1963 on the bottom.
