Data from "Locomotive Building", Railroad Age Gazette, Volume XLV, No 11 (14 August 1908), p. 732.
Locobase notes the nearly identical dimensions of the Butte, Anaconda & Pacific locomotive delivered by the MLW's overlord, Alco, in the same year; see Locobase 8833. Although the RAG doesn't say, the 1" difference in the driver diameters suggests that the driving wheelbase was the same at 14 ft 6 inches as was the engine wheelbase at 22 ft 9 inches.
RAG also listed the "special equipment" supplied as components with the locomotives. Locobase includes the list to illustrate the various suppliers:
Air brakes Westinghouse-Amerlcan
Bell ringers Sanson M. C. Hammett
Boiler lagging Magnesia sectional
Couplers Tower
Headlights Piper
Injectors No. 10 1/2, Ohio
Piston and valve-rod packings United States Metallic
Safety valve 3 1/2 in Crosby
Sanding devices Leach
Lubricators Chicago
Steam gage 6 3/4 in, Ashcroft
Steam heat equipment Safety Car Heating & Lighting Co
Tires, driving and truck Bochumler-Vereln, open-hearth steel
Tender truck boxes McCord
