Keith,
Old Town serial number 145263 belonged to a 15-foot CS (or common sense) grade 50-pound model that was built in 1946 and shipped to Johnstown, Penn. It had open spruce gunwales and ash decks, thwarts and seats. It had a keel, and the original color was the classic dark green.
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

If you are selling your canoe and plan to use this build record information as part of an ad, please consider giving the WCHA credit for this information on eBay or craigslist or wherever your canoe is listed.
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.
Lots of WCHA members can advise you on restoring the canoe. I recommend you also look in the WCHA bookstore, available online.
