The Old Town canoe with serial number 160977 is a 16 foot long, CS (Common Sense or middle) grade, Otca model with a keel. It was built between October and December, 1953. The original exterior paint color was dark green. It was shipped on April 23rd, 1954 to Unadilla, 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 others 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/wcha/ to learn more about the WCHA and http://www.wcha.org/join.php to join.
It is also possible that they could have another number or manufacturer if this description don't match the canoe. Feel free to reply here if you have any other questions.
