Data from Baldwin Locomotive Works Specification for Engines as digitized by the DeGolyer Library of Southern Methodist University Volume 34, p. 377. Works numbers were 34822-34885 in June 1910.
The other one of these two wood-burning tanks was the Jose Jardin. For some reason, Baldwin didn't calculate the grate area, so Locobase used the firebox dimensions.
