These kit cars were originally created by John Coots (N Scale of Nevada). After John's passing in 2008, the tooling was eventually acquired by Wiseman Model Services (who, as of this 2013 writing, continue to sell them through their eBay store). The kit includes decals, white metal castings, etched brass details, wire and Micro-Trains trucks (couplers not included).
The model is based on a 65' / 3197 CuFt prototype built by Gunderson in the late 1980's (and most commonly associated with the Washington Central, aka WCRC).
