The Old Town canoe with serial number 41486 is a 17 foot long, CS (Common Sense or middle) grade, Otca model with open spruce gunwales, birch decks, ash thwarts, ash seats, a keel, and outside stems. It was built between January and March, 1916. The original exterior paint color was dark red. It was shipped on March, 10th, 1916 to Saint Louis, Missouri. 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. 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

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.
