Pat Duffin built this ART reefer using pilot model parts from the Chooch Enterprises Ultra Scale II line. Pat did the original patterns for the project. The model is a fine example of a modeler using AAR wheel contours running on a five-foot gauge. The Wabash and MOPAC twin herald lettering scheme was adopted in the early 1950's.

Pat Duffin scratchbuilt this P-13 T&NO Pacific. The prototype loco pulled the streamlined Sunbeam from Dallas to Houston and return. The model is all brass construction and it is built to 5-foot gauge AAR standards.
