Old Town #103050 was a 17-foot CS (common sense) grade HW model built in 1929 and shipped in 1930 to Macy's. It had open spruce gunwales and ash decks, along with a keel, outside stems, and a floor rack. It was originally dark red. A second record in the database indicates a letter was received in 1982 from an owner of the boat in New Jersey.
The scans of both records are attached below-- click on them to get a larger image. 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 and anyone else reading this will join or renew membership in 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 renew.
