The Old Town canoe with serial number 110783 is a 17 foot long, AA (or top) grade, Otca model with red western cedar planking, open mahogany gunwales, twenty inch mahogany decks, mahogany thwarts, mahogany seats, a keel, and a floor rack. It was built in 1932. The original exterior paint color was maroon with a hair line stripe. It shipped on June 1st, 1932 to Macy's in Long Island City, New York. A scan showing this build record can be found below.
This scan 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 or your nephew 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. The Otca models from this era are more narrow than the later ones. The Molitor model commonly had a three foot long bow deck and a two foot long stern deck. See
