The 2 foot gauge Moguls I mentioned came earlier. Other examples of Baldwin outside-frame power with inside counterweights include the 2-4-2's and 2-8-0's that went to the Antofagasta Railway in Chile/Bolivia and the earliest outside frame 4-4-0's and 4-6-0's used on the Oeste de Minas in Brazil. All the above date to the late 1880's or 1890's. I think the Mexican National had some 3 foot gauge consolidations that fit that description, as well. Baldwin shifted to the use of crank-mounted counterweights on outside frame locomotives a few years after the turn of the century.
