The XTC04657M75F hull identification number (HIN) indicates that you have the Old Town canoe with serial number 204657. This is a 14 foot long Chipewyan model. It was built in October, 1974. The original exterior color was yellow. It shipped on January 16th, 1975 to Keene, New Hampshire. The back side of this scan shows that it has scuff marks all over the outside of the hull. Scans of both sides of this build record can be found by following the links at the attached thumbnail images 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.
