My guess is that you have the Old Town canoe with serial number 129918. This is a 16 foot long, CS (Common Sense or middle) grade, HW (Heavy Water) model with open spruce gunwales, a keel, and sponsons. It was built between April and August, 1940. The original exterior paint color was dark green. It was shipped on July 8th, 1941 to Manchester, New Hampshire. 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 more 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 also possible that you 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. Good luck with the restoration,
Benson
