The Old Town canoe with serial number 80978 is a 16 foot long, AA (or top) grade, Otca model with open mahogany gunwales, mahogany decks, mahogany thwarts, and mahogany seats. It was built between October, 1923 and June, 1925. The original exterior paint color design was similar to the one shown at
http://www.wcha.org/catalogs/old-town/designs/design02.gif which was know as the design number two. It shipped on June 15th, 1925 to Long Island City, New York. The note on the back side of the card indicates that it may have moved to East Calais, Vermont by May, 1987 when there was a previous request for a copy of this build record. Scans showing both sides of this build record can be found by following the links at the attached thumbnail images 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
http://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 your canoe. Please provide a picture if the original design is still showing. Feel free to reply here if you have any other questions. Thanks,
Benson
