Data from Baldwin Locomotive Works Specification for Engines as digitized by the DeGolyer Library of Southern Methodist University Volume 28, p. 55. See also the Mississippi Rails website's entry on the MC at [], last accessed 2 July 2011. Baldwin works numbers were 25665 in May 1905; 26733, 26740 in October; 30353 in March 1907; and 31022-31023, 31037 in July.
Data from builder's card archived at the Wilmington & Western, physically located in Marshallton, DE and on the web at []. Works number was 45921 in January 1909.
Data from "An Old Detroit Locomotive" Railway and Locomotive Engineering, May 1899, page 199. Works number was 12.
Wood-burner profiled many years after its service and more than 20 years after it had been scrapped. Sinclair speculated the locomotive was broken up in 1876 probably because of its crank axles. Among the construction details were of the "Sweet" truck, a closely spaced bogie made of boiler plate and suspended below the truck boxes. He quotes an engineer who ran one of the class about its virtues: "They were smart as a steel trap; were built upon honor, could run like lightning, pull a full train up a hill, and they rarely ever broke down on the road." And eat coal from a teaspoon and wrestle grizzly bears, too, most likely. Gene Connelly's roster suggests another history for the Persian. He records that it was rebuilt in 1877 with 18" x 24" cylinders and fitted with 57" drivers. Its new class was G9.
