Your canoe is an 18 foot CS Grade (middle grade) HW Model (Heavy Water) with keel and was originally painted bright red. It was built in 1952 - 53 and sold to a man in Springfield, MA.
This scan 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 join or 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 andhttp://store.wcha.org/WCHA-New-Membership.html 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.
