Jamie,
The build record shows that Old Town #113850 was an 18-foot AA (or top quality) OTCA with mahogany gunwales, decks, thwarts and seats. It had a keel, outside stems, and may have had half ribs (there's a notation but I can't tell if it's real). The canoe was built between 1934 and 1936 and shipped in 1938 to North Chelmsford, Mass. It was dark green in color.
The scan of this record is attached below-- click on it 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.
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.
If you wander around the WCHA site a bit, you'll find lots of people with expertise in restoring these canoes, as well as professionals who might help with certain aspects of the job. It would be great if you could also post a picture so we could see your boat.
