Another Maui-based sugar grower, this plantation purchased its first Baldwin in 1896 (Locobase 13159) and took possession of this Prairie tank nine years later.
"Lurch Bird" noted that the P C Jones was later converted to tankless 0-6-2 trailing a fur-wheel tender and asked why this might have been done. Charles Mutschler replied on 5 August 2008:
"My guess about the pilot truck is that because all of the prototypes operated at very slow speeds, there was not as much need for a pilot truck as there was a need for the trailing truck to carry the weight of the firebox and fuel bunker ... On the temporary track in the cane fields, I would bet the train speeds were rather slow, probably not much above a walking pace. On the main line to the sugar mill, I suspect these little locos didn't exceed fifteen miles per hour. "
