The Old Town canoe with serial number 77407 is an 18 foot long, CS (common sense or middle) grade, Otca model with red western cedar planking, open spruce gunwales, twenty inch birch decks, birch thwarts, birch seats, a keel, outside stems, and a floor rack. It was built between March and June, 1923. The original exterior paint color was dark red. It shipped on June 30th, 1923 to Shohola, Penna. A scan of this build record can be found by following the link at the attached thumbnail image 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 possible that you could have another number or manufacturer if this description don't match your canoe. Feel free to reply here if you have any other questions.
