The Old Town canoe with serial number 33790 is a 17 foot long, AA (or top) grade, HW (Heavy Water) model with red Western cedar planking, open mahogany gunwales, mahogany decks, mahogany thwarts, mahogany seats, half ribs, a keel, and outside stems. It was built between August, 1914 and May, 1915. The original exterior paint color was Yale blue. It shipped on June 23rd, 1915 to Weirs, 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 as you probably know well. 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 doesn't match your canoe. Feel free to reply here if you have any other questions.
