Maybe it is time for another obscure question about covered hoppers - this time the Rock Island 1958 cuft covered hoppers. In RP Cyc 27 on page 83 it shows number 436 delivered with the words "WHEN EMPTY RETURN TO DES MOINES IA". The cars as painted by Intermountain have the destination as "BAUXITE ARK". Would anybody have any idea what other destinations were originally stencilled? Thanks.
