Its 1963 and the uncatalogued sets that were NOT assembled by Lionel to be sold by major retailers like Sears, Montgomery Ward, Spiegel, J.C.Penney or Firestone were termed "General Retailer" sets. These sets often differed from catalogued sets by the substitution of one different car. One of these General Retailer uncatalogued sets was set # 19263 which is often termed the Libby Set. It contained the #6050 Libby's Tomato Juice 0-27 type boxcar and the #6475 Libby's Crushed Pineapple Vat car. It also included a #6076 plain grey / black rubber stamped ATSF hopper car and a #6167 plain yellow rubber stamped UP (SP type) caboose. This set was pulled by a plastic #1062 locomotive and a "Southern Pacific" tender. Interestingly while the Libby's cars are uncommon and collectable but the SP # 1060T Tender is very uncommon and quite collectable. The locomotive was rather widely used.
Evidently the set failed to meet sales expectations as each item is a known component in another set. The UP caboose however had an unusually long run, it first appeared in this set in 1963 and then was finally depleted in 1969 as part of a catalogued set.
So here today on R.S.M. we have the #6475 Libby's Crushed Pineapple Vat Car from 1963:
Here is a close up of the Vat's showing the labeling. The car itself came in 4 variations but these were mostly in smaller details. The cars were either light blue (as this one is) or aqua and the trucks were either arch bar or AAR . The Vat's were unchanged. Surprisingly 3 of the 4 variations came with only "dummy" couplers (as this one does) while the 4th variation had disc couplers.
