Having bought one of the smaller off-the-shelf sugar-plantation tanks a few months earlier (Locobase 13014), the Puerto Rico-based CC returned to Baldwin for its second such engine. This too was a standard design, but of slightly larger dimensions.

Ernest Wiener sold many small tanks to sugar roads in islands like Cuba and Puerto Rico. The latter was the location of the Central Cambalache, which operated near Arecibo, a city on the north coast west of San Juan.
The specifications notes curves on an extremely tight 75-ft radius, which helps to explain the long engine wheelbase.
