It will probably take more than just a number like this to identify your boat / canoe. Can you provide any dimensions or pictures? An xx-yyy format was also used by Peterborough and White companies. The Old Town canoe with serial number 46277 is a 16 foot long, CS (Common Sense or middle) grade, Livery model with red Western cedar planking, closed spruce gunwales, ash decks, ash thwarts, ash seats, a keel, and a floor rack. It was built between November, 1916 and June, 1917. The original exterior paint color was dark green. It shipped on June 28th, 1917 to Plattsburg, New York. 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. 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 boat/canoe. Feel free to reply here if you have any other questions.
