At the Chicago O scale show today I saw a huge tome on CB&Q cabooses, that ought to be in Malcolm's
collection, and mine (but I balked at the price). I have a book on MoPac cabooses that shows that road
as having a tremendous variety of cabooses, including many side door, combine, and drovers' cabooses.
This CB&Q book was about an inch and a half thick, looked like a library copy of a dictionary, and I set
it down quickly when I found it was priced at $125.00, so I don't know what is in it, but the cover showed
a side door caboose, which made me want it. Sadly, I left it, although the size gave me hope that the Q
had many varieties of cabooses, also.
