Data from Baldwin Locomotive Works Specification for Engines as digitized by the DeGolyer Library of Southern Methodist University, Vol 63, p 231. See also Benjamin Levy, "Old Sugar Mill of Koloa", Netional Register of Historic Places Nomination Form (submitted August 1978) at [] . Works number was 52875 in January 1920.
In the nomination form, the applicants noted that this Kauai-island mill was the oldest commercially successful sugar plantation in the Hawaiian Islands. It took shape in 1835 when three men formed Ladd & Company and negotiated a lease of 980 acres (396 ha) of land on Kauai from King Kamehameha III.
Although responsible for the first three mills on the property (including the 1841 mill that is the focus of the registry nomination), Ladd & Company gave up its interest in 1845. Dr R W Wood's efforts after 1848 led to continuing success and profitability for over a century.
More than seventy years later came this little coal-burning tank, which was fitted with a Rushton Improved spark-arresting stack.
