A new book has been released in just the past week or so, and it is pretty good. Perhaps this is something a few might want to put on their Christmas list.
White River Publications, the group that does Model Railroad Craftsman among other media, has this "new" book on the market . . .

Note: I believe the authors are well-known on this website.
This is an excellent book, full of photographs and details. If you like seeing vintage diesels, running long hood forward, you'll appreciate this publication. And, yes, it it pricey but well worth it.
I will have to check this out. Thanks for the info.
