Tracks A Pere Marquette Historical Society Publication: The Pere Marquette's Wooden Cabooses by Al Kresse
This is an excellent overview of the wooden cabooses used by the PM over the years from the early years up through the last cars purchased.
There are great photos showing these cars in various PM paint schemes as well as C&O styling of several varieties, and a table that explains when the various types of paint jobs were used.
There is an article included on modelling a PM wooden caboose as well as an extensive bibliography listing where further information on this equipment can be found.
Al Kresse is a noted author who has done several books and scores of articles both for the C&O Historical Society and the PM Historical Society.
