Data from Baldwin Locomotive Works Specification for Engines as digitized by the DeGolyer Library of Southern Methodist University Volume 63, pp. 251+. See also a photo tour of the closed works: Gloria Merryman "June 1st, 2010 Central Roig, Historic Sugar Cane Plantation and Mill, Yabucoa, Puerto Rico, El Yunque, Rain Forest" at [] . Works numbers were 54242 in January 1921 and 60565 in July 1928.
This sugar processing central in southeastern Puerto Rico was owned by Yabucoa Sugar Company. They bought these very small saddle tanks. The 9 was delivered with a Rushton Improved spark-arresting abbage stack.
Gloria Merryman notes that this was the last sugar mill to operate in Puerto Rico (it closed in 2000) and was the largest in this particular valley. Her grandfather worked for CR and her father grew up at the mill. She adds:"During harvest it felt like it was snowing except that the flakes were black and the weather was warm."
"I remember him bringing me sugar cane. It was such a treat to chew on the cane and, oh, so sweet."
The Central Roig sold the 8 to Sterling Coal Company, where it could still be seen in operation in 1946.
