The Old Town canoe with serial number 106703 is an 18 foot long, AA (or top) grade, Otca model with red Western cedar planking open mahogany gunwales, a keel, and a floor rack. It was built between June, 1930 and January, 1931. The original exterior paint color was Princeton orange with the name "Kelek" painted on. It shipped on January 17th, 1931 to Weybridge, Surrey, England. A scan of this build record can be found by following the link behind the thumbnail image 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/ot_records/ if you want more details. I hope that you will 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 http://store.wcha.org/WCHA-New-Membership.html to renew.
It is also possible that you could have another number or manufacturer if this description doesn't match the canoe. Please attach some pictures if the original exterior name is still showing. Feel free to reply here if you have any other questions.
