Another, not unrelated question
I look at pictures of Great Western vans and see doors with external framing including a diagonal brace.
However the vans as sold by Hornby, Bachman and Dapol, have no external framing and appear to be exactly the same as those used on British Railways vans.
Is this a silly mistake "helped" by the re-use of the same tooling, or did the Great Western bring in plain doors, and if so when ?
