Sorry, I have not found views showing any kind of fall plate though. Surely there must have been something available to bridge the gap over the couplings?!
Matt.S, I wish I had been able to come across any similarly superb, large scale drawings like the one you posted when I was researching the 20ft F type vans and the D type carriages too!!
Although it is perhaps just a bit of academic interest now that "Brandbright" has changed hands and the old projects have been shelved for the foreseeable, (?) I cannot help but maintain my fascination with the subject!
Pete.
