Old Wood Working Machines. Covering only North American manufactures, the OWWM website (referred to as the mothership) has 1160 scans of manuals, flyers, catalogs, and sales literature dating back over 100 years. The FAQ is extensive and has exploded spinning off many pertinent articles. OWWM also has almost 2200 user submitted, machinery profiles showing machines as found and/or restored. One of the highlights is a write up on what appears to be the very first (PDF) Delta Unisaw which was built before WWII and aside from mostly cosmetic changes is still built today.
