Data from Baldwin Locomotive Works Specification for Engines as digitized by the DeGolyer Library of Southern Methodist University Volume 14, p 216. Works number was 9601 in November 1888.
A Pennsylvania sawmill company headquartered in Ridgway, Penna, W H Hyde found itself in need of a small four-coupled tank with trailing truck.They specified coal capacity sufficient for a 20-mile (32 km) run. Noting the plain grate in this example, a 23 November 1888 "hereafter" note in the specs advised Baldwin to use drop plates instead. The engineer sat on a box seat fitted with a cushion and lid.
