Rut row. Just noticed something. The overly huge bow rail on the 20000 Walt Disney vagabond could be original. Look at the ski Bo in the 67 catalog. Looks like the same one. Hmm very interesting. Could have been an option.
I think the only walk thru front seats (w/ aluminum front seat backs) w/ those sideways benches was the 1957, like the one I bought.
Otherwise, it was a flat bench, w/ a ply seat back, not an aluminum back rest. And the seat bench was continuous, like the one in StLouis. The back might have had a dip in the middle to make it easier to step over/through, but the bench was all the way across
