The Old Town canoe with serial number 117861 is an 18 foot long, AA (or top) grade, Otca model with red Western cedar planking open mahogany gunwales, mahogany decks, mahogany thwarts, mahogany seats, a keel, and a floor rack. It was built between January, 1932 and May, 1933. The original exterior paint color was similar to the one shown at
http://www.wcha.org/catalogs/old-town/designs/design39.gif which was known as the design number 39. It shipped on June 7th, 1933 to Big Moose, New York. A scan of this build record can be found by following the link behind the thumbnail image attached 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 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 exterior design is still showing. Feel free to reply here if you have any other questions.
