The Old Town canoe with serial number 77107 is a 16 foot long, CS (common sense or middle) grade, Yankee model with open oak gunwales, oak decks, oak thwarts, oak seats, half ribs, a keel, and outside stems. It was built between March and May, 1923. The original exterior paint color was light green with a yellow border stripe. It was shipped on June 1st, 1923 to Los Angles, California. 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 more were created with substantial grants from the Wooden Canoe Heritage Association (WCHA) and others as you probably know well. 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 renew.
It is also possible that you could have another number or manufacturer if this description doesn't match your canoe. The highest Carleton build record is for serial number 20540. See the messages at
