The A.T. & S.F. Caboose No. 6357-50 has a RED painted Die 4 body and was produced in 1960 as part of the combined O and HO sets that are known as the "over and under." Equipped with early AAR trucks with one disc coupler, this caboose did not have the "C-40-1", "BUILT 9-47", and "SP" markings that are seen on the other cabooses that are numbered "6357." It came in an ORANGE perforated box that is marked "6357-50". There are no known variations of this hard to find caboose.
