Welcome, the Old Town canoe with serial number 139254 is a 17 foot long, CS (common sense or middle) grade, Otca model with open spruce gunwales, number 10 canvas, ash decks, ash thwarts, ash seats, a keel, a floor rack, and two bobstays. It was built between January and May, 1944. The original exterior paint color was dark green. It shipped on May 15th, 1944 to Portland, Maine. The floor rack and bobstays appear to have been removed in the pictures that I saw in June with the craigslist listing. A scan of this build record can be found below.
This scan and several hundred thousand more 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/catalogs/old-town/records/ if you want more details. I hope that you will donate, 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 this description doesn't match the canoe. Feel free to reply if you have any other questions.
