Lionel Case / International Harvester GP-9 and bay window caboose prototypes. These are hand painted with the decals taped to the locomotive and caboose. We guess these would date to the 1996-1998 time period judging by the GP-9 chassis that was used. More than likely this was being considered for the 21795 Case set that was eventually led by a steam locomotive. This set is one of a kind!
