I am building an NW right now, will be an ex-IHB unit we had locally when I volunteered down at the short line RR here in town. Did anybody ever do roller bearing side frames for these? I would like to do the two other units the line had, but they had roller bearing trucks and twin sealed beam SW type headlights. I think I saw someone on Shapeways offering the headlights. I plan to build all of them from All Nation units, I like the heavy diecast. Jay C. is rebuilding my chain drives for my current one for me. That should cure the split sprocket issues. Mike
