Scans of these build records can be found by following the links behind the thumbnail images attached below. These scans and several hundred thousand others 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 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 these descriptions don't match your canoes. Feel free to reply here if you have any other questions,
