Data from Baldwin Locomotive Works Specification for Engines as digitized by the DeGolyer Library of Southern Methodist University Volume 21, p 296. Works number was 22445 in July 1903.
Locobases 12319-12320 showed several narrow-gauge saddle tanks of very similar dimensions that had gone to work on Hawaiian plantations a few years before the Lawai arrived. Its 200-psi boiler significantly boosted the power available to the skinny-rail system on which it worked.
In 1934, the Lawai went to the Lilue Plantation as the Iliahi.

Sugar producers Alexander & Baldwin bought this plantation radial tank for a southern Kauai sugar company (see Locobase 12406 for a history of the plantation). The specification pages discuss several construction details designed to reduce the risk of accidental fires in addition to the fitting of a standard Radley & Hunter flared stack. The ash pan was fitted with netting to catch hot ash and two dampers with a water pipe leading from the tank and arranged to sprinkle water. The smokebox was extended so that the cleaning door was at least 30 inches (762 mm) from the center line of the stack. Water blowers on the bottom and sides blew out ashes, a heavy netting screen mounted above the top row of tubes as a spark arrester was to be "conveniently arranged" to allow for the cleaning of tubes.
This engine wound up on the Lihue Plantation sometime after 1939.
