Congratulations, the Old Town canoe with serial number 131732 is a 16 foot long, CS (common sense or middle) grade, Otca model with open spruce gunwales and a keel. It was built between June and October, 1961. The original exterior paint design is shown at
http://www.wcha.org/catalogs/old-town/designs/design46.gif and was known as the design number 46. It shipped on February 18th, 1942 to Boston, Massachusetts. The back side of the record indicates that there was a previous request for a copy of this build record from Pembroke, Massachusetts on March 20th, 1972. Scans showing both sides of this build record are attached below.
These scans and several hundred thousand more 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
https://www.wcha.org/catalogs/old-town/records/ if you want more details. I hope that you will donate, join or renew your membership to the WCHA so that services like this can continue. See

It is also possible that you could have another number or manufacturer if this description doesn't match the canoe. Please attach some pictures if the original paint design is still showing. Feel free to reply here if you have any other questions. Good luck with the project,
Benson
