In response to Louis mentioning the photo of a Prairie with four single phase air pumps mounted in a row on one side, here are a couple of O.H. Means photos from Corbin's collection, both taken at Barstow, Ill., in 1923 and both depicting 1800 series R-3 Prairies at the wooden coal chute there. The 1813 typifies the R-3s at that time, with a pair of single lung air pumps mounted on the left side just below the steam dome, while the 1808 (misidentified in previous publication as the 1803) has two additional pumps in front of the standard two. Was this a test application? Or was it an early version of the Prairies with additional air pumps for operating dump cars? We'll probably never know unless company correspondence about the application turns up somewhere. Whatever the case, it makes for a strange looking locomotive.
