Scans of these build records can be found by following the links at the thumbnail images attached above. These scans 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 join or renew your membership to the WCHA so that services like this can continue. See

It is also possible that you could have other numbers or manufacturers if these descriptions don't match your canoes. Feel free to reply here if you have any other questions.
