Steve, what a cleaver idea to easily combat the visual geometry problems of an 8' door on a 6' door car body. Makes me think "Why didn't I think of that"!
Since you brought it up. 61216 after repaint to green with the map scheme. Photos seem to indicate the lower side sill extension was applied when built; note that 61206 above has NEW for reweigh. Open door? Yes, I cheated. The open door hides the lack of body work to make the door opening on the Intermountain shell actually 8 ft. Jerry Glow decals, but I don't see them on Tichy now.
