The Old Town canoe with serial number 209618. This is a 17 foot long Chipewyan Tripper model with aluminum inserts in the vinyl rails. It was built in September, 1975. The original exterior color was avocado. It shipped on September 25th, 1975 to North Conway, New Hampshire. The back side of this scan shows that the skin was torn under the stern deck and that the warranty card was returned from Bridgton, Maine in April, 1976. Scans of both sides of this build record can be found by following the links at the attached thumbnail images below.
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

It is also possible that you could have another number or manufacturer if this description doesn't match your canoe. I am just outside of Bridgton now at the Maine Canoe Symposium in the rain. New rails can be ordered from your local Old Town dealer as Paul mentioned. Feel free to reply here if you have any other questions.
