Back in the mid-eighties, I had a book that I considered as the "Diesel Spotters Guide" for British Rail locomotives. I remember seeing several pages devoted to locomotives such as the "Kestral" and the Metropolitan Vickers 10000 (?). This book also went into some detail concerning lesser known locomotives, such as the Clayton (Cl 17 ?) and the early models (LMS) of the Cl 08's & 09's. I doubt very much if this particular book is still in print, but is there available a "Diesel Spotters Guide" for British Diesel locomotives. The newer locomotives don't really interest me too much, just the earlier ones. Also the name and postal & e-mail address of a stockist for this book(s) would be most helpful. Another question if i may: Did the U.S. built (by General Motors) SW
1000 (?) as owned by Yoeman have a classification (i.e. such as CL 20)? Thank you for any and all information that you can give me.Lawrence White
