I'm looking for a general arrangement drawing of a BR 12T van with corrugated ends. I've dug through the NRM OPC microfiche list but with no luck and I've started on the NRM Derby Carriage Works list but that is hard going with no search facility and nearly 900 pages. I've got the Essery LMS wagon books and the Tatlow LNER book, so I have a fair amount of information on the BR van's predecessors, but it would be good to have details of the actual wagon with any differences BR incorporated. I'll also be looking for other early BR wagons but the van will do to start with. This has nothing to do with my Caledonian exploits - obviously -, but another possible project for S scale. Isn't it great how we can access drawings from over a hundred years ago with little problem, but have great difficulty finding ones for railway prototypes built in our own lifetime. I've been looking for the drawings for a 303 class "Blue Train" since the 1960s and haven't located one yet. Jim.
