The Old Town canoe with serial number 182722 is a 15 foot long lightweight model with a keel. It was built between February and March, 1969. The original exterior paint color was maroon. It shipped on June 23rd, 1969 to Blue Mountain Lake, New York.
The Old Town canoe with serial number 18277 is 18 feet long so that probably isn't the build record you want. Scans showing both of these build records are below.
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 donate, join or renew your membership to the WCHA so that services like this can continue. See http://www.wcha.org/about-wcha to learn more about the WCHA and http://www.wcha.org/store/membership to join.
It is also possible that you could have another number or manufacturer if this description doesn't match your canoe. Feel free to reply here if you have any other questions.
