Data from DeGolyer, Vol 64, pp. 126+. Works number was 54257 in January 1921.
This oil-burningl plantation saddle tank was ordered by the Central La Francia as their #6, but redirected before delivery to arrive at the San Cristobal.
Data from DeGolyer, Vol 63, pp. 388+. Works number was 52104 in July 1919.
Mixed in with the long run of superheated Ten-wheelers shown in Locobase 14424 was this lone oil-burning saddle tank.
