Chris Brooks and Richard Szwejkowski (Pathfinder Publishing)
A phographic history of class 50 tours run by F&W and Pathfinder Tours from the late 1970s to 1994 and was originally printed to coincide with the last of the BR erun class 50 farewell tours.
The book has a simple but effective format of one or two pictures and captions per page, and the tours largely appear in date order.
 
These books are now historic artifacts in their own right being printed over 25 years ago.  Storage has not been kind to the covers which are marked, as are some of the internal pages.
