Brass patented a technique for the first industrial scale distillation of metallic zinc known as "distillation per descencum" or "the English process." This local zinc was used in speltering and allowed greater control over the zinc content of brass and the production of high-zinc copper alloys which would have been difficult or impossible to produce using cementation, for use in expensive objects such as scientific instruments, clocks, brass buttons and costume jewellery. However Champion continued to use the cheaper calamine cementation method to produce lower-zinc brass and the archaeological remains of bee-hive shaped cementation furnaces have been identified at his works

Little is known about its early life, but from around 1970, it worked at Wabash Alloys, a producer of aluminum alloys, at Haskell, Arkansas. It eventually became surplus to the company's needs and they donated it to the Arkansas Railroad Museum at Pine Bluff, Arkansas on March 8, 2003. The 25-ton model was the smallest locomotive in the GE range in the 1940s and 50s. It was designed for the small industrial user. With and of tractive effort, it could pull half a dozen
