Old Town 153172 is a 16 foot CS (common sense or middle) grade square stern model canoe that was completed August-October 1949. It has red Western cedar planking, open spruce gunwales, a keel, outside stems, and a floor rack. Wood species for deck, thwarts and seats isn't specified but CS grade would include any hardwood other than mahogany. Original color was a two-tone paint job of dark green with guide special green on the bottom. The canoe was shipped to Russell's Camp in Brookton, Massachusetts, on May 3, 1951. Although the canoe was basically completed in 1949, the shipping date is traditionally considered a canoe's "birthday". A copy of this scan is attached below-- click on it to get larger images.
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/wcha/ to learn more about the WCHA and http://www.wcha.org/join.php to join.
