OK: What do you know about SOU 311006?<<
It's a standard Southern railway wood sheathed DS
automobile/furniture car of the same general type offered by
Sunshine as a resin kit. In this case it is owned by the Alabama
Great Southern as evidenced by the number series and the small "AGS"
at the top of the side above the dimensional data.
My guess is that it could be in furniture service – Southern served
factories in North Carolina among other places
