Data from Baldwin Locomotive Works Specification for Engines as digitized by the DeGolyer Library of Southern Methodist University, Volume 31 p.200. See Locobase 13278 for a description of the Monserrate. Works number was 33097 in December 1908.
Although the Monserrate had bought a 2-4-0 for its metre-gauge operation, it apparently needed a smaller tank engine for its lighter-weight 60-cm line. This little backup tank did the job.
