Data from Baldwin Locomotive Works Specification for Engines as digitized by the DeGolyer Library of Southern Methodist University Volume 21, p. 194. See also "Pacific Sugar Mill" on the Hamakua website at [], last accessed 25 September 2025. Works number was 15984 in June 1898.
WG Irwin & Company, on behalf of FA Schafer & Company brokered this sale. .The Pacific's 9" (229 mm) diameter Radley & Hunter stack suppressed the sparks that all too easily set fires in densely wooded and cultivated surrounding.
PSM&P owned well-watered acres on the northesast section of the Big Island. he sugar-plantation engine worked for the PSMC for three decades before being sold to the Honokaa Sugar Co and renamed Kukuihaele.
