Data from DeGolyer, Vol 66, pp. 352+. Works numbers were 52355-52356 in September 1919.
At the same time the Santa Catarina bought the two Moguls shown in Locobase 15178, it bought these somewhat larger (but still very small) wood-burning Eight-wheelers. Although both were described as "passenger and freight" engines, the 6 and 7 had taller drivers and a bigger boiler.
