Data from Baldwin Locomotive Works Specification for Engines as digitized by the DeGolyer Library of Southern Methodist University Volume 54, p. 257. Works number was 41380 in May 1914.
An outside-frame plantation Consolidation bought by the Bartram Brothers to operate on their estate at La Fe, Cuba, the Magua was instead delivered to a Dominican Republic address. Ten years later the Don Alberta was produced to the same design; see Locobase 14482.
Data from Baldwin Locomotive Works Specification for Engines as digitized by the DeGolyer Library of Southern Methodist University Vol 72, p. 70. Works numbers were 57896 in July 1924, 58617 in August 1925, and 62224 in December 1937.
Ten years after the plantation Consolidation Magua had first run on the Consuelo Estate (Locobase 14481), the Don Alberta was produced to the same design, but was heavier and oil-fired. The latter meant a new longer tender that weighed considerably more. A year later, "Skipper" joined the Don Alberta. The John Dinzey very likely was built to the same design a dozen years later.
