Corbin & Kerka (1960, 84) in which they note that boiler was rebuilt in 1897 to eliminate the combustion chamber, which had not functioned as planned. It was later rebuilt as a 4-4-2 Atlantic; see Locobase 5453.
See also Engineering News December 1895 extract from http://www.railroadextra.com/lococol.htm, from which information about the tube number and length as well as other data was taken. In addition, the article tells us the combustion chamber contributed 36.79 sq ft to the total heating surface.
