3D-printed Plastic Kit
S Scale Resource, Dec 2018
The company produces the 3D-printed parts, available via Shapeways, to allow you to build a full model of this engine. The modeler needs to supply the frame and drive mechanism, and any additional detailing parts. The web site link is to their main page, so you will have to look through the labeled items to find the parts specific to this model (please note that not all items are S-scale).
