19-65 Uniflow Baker powering the sawmill at the Dover, Ohio TVPPA show, August 22, 2015.
The video also shows closeups of sawmill operation.
In later years of production, Baker made 3 sizes of engines, 19-65, 21-75, and 23-90. Most were Uniflow, which exhausted steam through ports at the center of the cylinder, while some were conventional counterflow. All castings have a code, a combination of A, B or C, which indicates which engine size(s) the part is used on, plus a casting number. In this case, the engine frame / crosshead guide code is A, meaning that it is only for the 19-65, while the support bracket below it is marked ABC, thus is applicable to all 3 engine sizes.
Many sow bugs were harmed in the making of this video.
