This model was originally imported by Atlas back to the early days of N scale (late 1960s). Con-Cor imported it later on. Walthers also imported it (briefly) during the 1990s (in Roco packaging). Eastern Seaboard Models sells these cars in custom paint schemes not directly available from Roco. Mehano (Yugoslavia) manufactured a nigh exact copy of this car for many years (imported by AHM, MRC, Model Power and Life-Like).
From the 1940s through the 1970s, PS3 50-ton hoppers were favorites for handling carload shipments to retail dealers.
