Data from Baldwin Locomotive Works Specification for Engines as digitized by the DeGolyer Library of Southern Methodist University Volume 11, p 244. Works number was 6944 in September 1883.
J De Rivera was the purchasing agent for this locomotive, but it was delivered to the Waimanalo Company on Oahu and spent the next 50+ years toiling as a sugar-cane plantation workhorse. It's not clear from Connelly's Baldwin list when the 2 acquired the name Pokaa.
In 1948, Ward Kimball bought the Pokaa to run on his San Gabriel, Calif railroad.
