The Old Town canoe with serial number 178379 is 15 feet long, Lightweight model, equipped with half ribs, keel and outside stems. The canoe was built in 1967 and finishing was completed on November 30, 1967. The original exterior paint color was “L.C. Yellow" (light chrome yellow?). It was shipped to Hack’s Canoe Retreat in Mt. Holly, New Jersey Marion, Ohio on December 7, 1967. 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/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/ to learn more about the WCHA and http://store.wcha.org/WCHA-New-Membership.html to join.
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.
