The Old Town canoe with serial number 125658 is a 17 foot long, CS grade, Otca model with open spruce gunwales, birch decks, birch trim, a keel, and a floor rack. It was built between November, 1938 and January, 1939. The original exterior paint color was dark red. It shipped on April 6th, 1939 to Newark, New Jersey.
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 renew.
It is also possible that you could have another number or manufacturer if these descriptions don't match your canoe. Feel free to reply here if you have any other questions.
