The Old Town canoe with serial number 129207 is a 16 foot long, AA (or top) grade, HW (Heavy Water) model with open mahogany gunwales, mahogany decks, mahogany thwarts, mahogany seats, a keel, and a floor rack. It was built between February, 1940 and February, 1941. The original exterior paint was similar to the one shown at http://www.wcha.org/catalogs/old-town/designs/design43.gif
which was known as the design number 43. It shipped on August 6th, 1941 to Oneonta, New York. A scan showing this build record can be found by following the link at the attached thumbnail image below.
This scan and several hundred thousand others were created with substantial grants from the Wooden Canoe Heritage Association (WCHA) and others. A description of the project to preserve these records is available at http://www.wcha.org/ot_records/
if you want more details. I hope that you will join or renew your membership to the WCHA so that services like this can continue. See http://www.wcha.org/about-the-wcha/

It is also possible that you could have another number or manufacturer if this description doesn't match your canoe. Feel free to reply here if you have any other questions.
