Dr. Wayne's Diagnosis Needed.

[Mileswestern]

Dr. Wayne, I plan to build a fleet of "door and a half" Wood-sided, steel underframe/end boxcars, and was wondering which car would be an ideal starting point for such a conversion? A friend suggested the Tichy USRA rebuild model, but do you have any other suggestions too?

How should I approach the half-sized (4' usually) door? I know you've made a number of these, and I'd love to see what you can dig up.

Thanks!
