Old Town 66470 is a 16 foot CS (common sense or middle) grade HW (heavy water, or lake boat) model canoe that was completed June of 1921. It has red Western cedar planking, open spruce gunwales, birch decks, birch thwarts, birch seat frames and a keel. Originally it was dark green. It was shipped to a camp in Greenwich Village, MA, on July 8, 1921. (That was a day before my mother was born, and finding interesting things like that out is what makes looking these up fun for me too!)Image of the scan of this record is attached below-- click on it to get a larger image.
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/wcha/ to learn more about the WCHA and http://www.wcha.org/join.php 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.
