Collector remembers stationary steam used to drag logs with a model steam donkey.
A steam donkey built from an Ozark Miniature kit, as purchased. In real life these were usually rust-colored or black, but Jon painted this one red to enhance the details.
An AMT/Ertl 1/25-scale Caterpillar D8H plastic kit. Jon added metal tracks to replace the original plastic ones, a canopy, sweeps, front brush guard on top of the blade, hydraulic lines and other small details.
