Notes:

Note that this body shell is identical between each of the F-series models the company released. In actuality, the models were Phase IV F3 engines. Most of the models had a hump in the center. This was due to the shell being pulled from the die before it was fully cured.

Notes:

The model was sold as ready-to-run, but Omnicon used the NorthWest ShortLine drive system, the Wabash Valley F-unit styrene shell (which was a re-worked Enhorning shell), and a frame and brass truck sideframes from SouthWind Models. The gearing was set to match the American Models' FP7 engines of the time, so that these could run in a consist. Omnicon sold a separate super-detailing kit (part #1007S). These models could be used for building a late-F3 model or an early F7 one, with some extra effort by the modeler.

This company is the originator of this "open source" locomotive design. Since it is open source, you will find others whom have enhanced the design, and yet others who make the actual 3D-printed models available for sale. This company only makes the 3D-printer files available.
