Old Town 171899 is a 17 foot Otca model canoe that was completed March-July of 1962. It has half-ribs and a keel and was originally painted white. It was shipped to Ottumwa, Iowa, on July 24, 1962. 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.
The information you gave me matches what I know about this boat from the owner. The canvas is removed from the hull but I can can see evidence of white colored canvas. I'm new to this type of restoration and to this site. I'll be posting many questions.
