Data from "0-4-2 T 20", Order number C-208, American Locomotive Company data card supplied by Chris Hohl in his 1 February 2025 email. See also Peter T Young, "Honolulu Iron Works", a 29 May 2015 post in the Images of Old Hawai''i" website at [], last accessed 17 May 2025. Works numbers were 66463-66464 in November 1925.
"Honiron" as it later came to be called, began in 1852 as a supplier to the Honolulu Steam Flouring Company. After the Iron Works burned in 1860, David Weston, then machinist in charge, repurposed the company as manufacturer of hardware for the milling companies. "By the turn of the century," Young reports, citing Dye, "the Iron Works was making complete sugar 'factories' for plantations in Puerto Rico, Cuba, Mexico, Louisiana, Formosa and the Philippines - as well as supplying Hawai?i's sugar planters.".
Young also reproduces a long, effusive Honiron profile originally published on 12 March 1897, about a year before the momentous US acquistion of the islands as a Territory. The company changed hands several times, but kept its independence until 1960.
Making its lilliputian contribution to Honiron's fortune were these little narrow-gauge coal-powered saddle-tanks sporting large, spark-arresting cabbage stacks, photographed in 1925 by Alco as "American #1.". Supposing that the HIW locmotive #2, which followed the 1 immediately on the Cooke production line also had a trailing truck. Honiron eventrually sold both to the Pampanga Sugar Development in the Philippines.
Overall, Honiron claimed, "Since its beginning, Honolulu Iron Works has participated in the construction of more than 200 cane sugar mills, 8 beet sugar factories, 8 refineries and 6 alcohol distilleries. (honiron)."
