As Northern Pacific is a favorite road and I have two Sunshine kits for the 10000-13999 boxcars, I wanted to add a similar truck to the Tahoe Model Works line. The closest I could find was under an Illinois Central car at the Illinois Railway museum (always a Sunday stop after the Naperville meet). That became TMW-114/214. The bolster end isn't right for the NP cars, but perfect for my Sunshine IC boxcar kit. All-in-all, the best I could do.
On a later vacation passing through Hill City, SD, found an NP boxcar and quickly trespassed to get a photo of the truck.
