The Old Town canoe with serial number 124009 is shown as 16 feet long, CS (common sense or standard) grade, HW (Heavy Water) model with open spruce gunwales, ash decks, seats, and thwarts, and equipped with a keel and sponsons. The canoe was built between December 1937 and May 1939. The original exterior paint was dark green. It was shipped to San Francisco, California on May 13, 1938. A scan of this build record can be found by following the link behind the thumbnail image attached 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/catalogs/old-town/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-wcha to learn more about the WCHA and http://www.wcha.org/store/membership to join.
It is also possible that you could have another number or manufacturer if this description doesn't match your canoe.
