Lorenz. Here is a photo via Bob Lorenz that was taken near Tiffin, Ohio, in 1952. Shown here (L to R) are Pennsylvania Railroad engine #9571 and two more "BF" Class units whose road numbers are not recorded. All were built by the Baldwin Locomotive Works. #9571 is a BF-15 constructed in March of 1949, rated at 1,500 horsepower, and retired in December of 1963 after just 14 years of revenue service.
