Data from Baldwin Locomotive Works Specification for Engines as digitized by the DeGolyer Library of Southern Methodist University Volume 74, p. 48; and "Six-wheeled, Four-wheels-coupled tank locomotive - Class 6-18-1/2-C" Road No 4, data card supplied by Chris Hohl in his 1 February 2025 email. Works number was 55581 in August 1922.
Empire #4 could be described as an 0-6-0T switcher that sacrificed one of its driving axles. Its straight boiler hosted the usual sand dome over the front drving axle and steam dome just ahead of the cab. Small drivers and crew dimension requirements led to a high boiler line that rested the smokebox end on a pedestal.
Gene Connelly's Baldwin production list reports that EMC bought the locomotive for Goldsboro, North Carolina's Atlas Plywoud Corporation. He notes too that the 4 continued to operate until at least 1945-1947.

Eden Manufacturing was owned by the O T Bourne & Company, which purchased this teeny, tiny standard-gauge radial tank. It would later operate for the Urmston Shipley Lumber Co before being sold to locomotive rebuilder/reseller Southern Iron & Equipment.
