(Reference). From 1929 through 1961 Gibson, Inc. of Kalamazoo, MI produced over 30 brands of musical instruments that did not carry the Gibson name. Many of these brands may be familiar, with names such as Recording King, National and Washburn, while many others are brands that only a handful of avid Gibsonites will know, such as Werlein Leader, Grinnell, Truett, and many more. This book is a complete guide to all of the other brands Gibson produced, complete with detailed descriptions, photos and rare examples of existing instruments from collectors around the world. If you're hoping to find that diamond in the rough at the local garage sale, this guide will familiarize you with even the most obscure brands Gibson made for more than three decades.
