The Garbely Publishing Company
The Garbely Publishing Company is one of the few publishers in the hobby aggressively publishing new titles. As the publisher is trying to make a living at this, print runs are made to sell out fairly soon. The publisher doesn't want to incur the costs of long-term storage of inventory. Expect Garbely titles to sell out quickly. The Conrail Caboose book is an example of this policy. There will be one print run and the number of backorders for the title will determine the size of the printing.
Arizona Hobbies never did stock the Northern Pacific and Southern Pacific dining car 'books'. One was little more than a pamphlet and both were over-priced.
