These are some of the other stock books that have appeared over the years.
Published by the Dalescroft Railfans Club, I've only managed to come edition across the fourth edition - I'd welcome hearing from anyone that has any other editions. Possibly the earliest stand alone book with allocations for each vehicle.
An allocation list published by the Worcester Locomotive Society, not sure if this was the only one. A successor to a supplement they published with their quarterly magazine in 1972.
Coaching Stock of British Railways. There are probably more issues of this, these are the ones I've picked up. Despite the title, DMUs are included in detail including allocations.
The National Railway Enthusiast Association. Was there more than this first edition?
An example of the OPC pocket sized book which contained DMU allocations.
Metro Enterprise's take on the popular pocket sized stock book which ran to at least three editions.
