Welcome, the Old Town canoe with serial number 131111 is a 16 foot long, CS (common sense or middle) grade, Otca model with open spruce gunwales, birch decks, birch thwarts, birch seats, oval outside finish rails, a keel, and a brass P. R. (painter ring?) in the bow stem. It was built between December, 1940 and February, 1941. The original exterior paint color was bright red. It shipped on February 24th, 1941 to New York City. 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
http://www.wcha.org/about-the-wcha/ to learn more about the WCHA and

It is possible that you could have another number or manufacturer if this description doesn't match your canoe. The records from this era often lack the sort of detailed information about additional accessories that were often included in the earlier records. A sail rig is not mentioned so that was probably added after it originally left the factory. Feel free to reply here if you have any other questions. Good luck with the decision,
Benson
