The Old Town canoe with serial number 201024 is a 16 foot long Otca model. It was built between April and August, 1974. The original exterior paint color was a red. It was shipped on August 9th, 1974 to Canandaigua, New York. 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. 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/wcha/ to learn more about the WCHA and http://www.wcha.org/join.html to join.
It is also possible that you could have another number or manufacturer if this description doesn't match your friend's canoe. Feel free to reply here if you have any other questions.
