In reference my previous message to the "nshore" list, I've purchased an ATSF heavyweight turtleback coach that looks close enough for a 700-series. A few questions: (a) What type of Air Conditioning on these cars? The pictures I've seen seem to lean toward mechanical and not ice-activated. (b) Does anyone have drawings they could post? If not, I'd be glad just to get vital dimensional data; specifically, length. (c) The model I have includes vestibules on both ends, but the few pictures I have seen show have no vestibule on the brake wheel end? Specifically, a 700-coach on the cover of FMIG Newsletter #25 has one renumbered for MofW service; the brake wheel end has 2 extra-long drop graps with a stirrup step below.
