The Old Town with serial number 109069 is a nine foot long dinghy so my guess is that 100069 must be the correct one. This is a 17 foot long, CS (Common Sense or middle) grade, HW (heavy water) model with red Western cedar planking, open spruce gunwales that were converted to closed, birch decks, birch thwarts, birch seats, a keel, and a floor rack. It was built between December, 1928 and February, 1929. The original exterior paint color was Princeton orange with a half inch black stripe. It shipped on March 16th, 1929 to Newark, New Jersey. A scan of this build record and a picture of the serial number can be found by following the links behind the thumbnail images attached 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 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 the canoe. Feel free to reply here if you have any other questions. Thanks,
