Welcome, the Old Town canoe with serial number 83345 is a 17 foot long, CS (Common Sense or middle) grade, HW (heavy water) model with red Western cedar planking, open spruce gunwales, birch decks, birch thwarts, birch seats, a keel, and sponsons. It was built in 1924. The original exterior paint color was dark red with a 5/8 inch white stripe. This may have looked similar to the one at
http://www.wcha.org/catalogs/old-town/designs/design34.gif which was known as the design number 34. It shipped on June 11th, 1924 to Chicago, Illinois. A scan of this build record can be found by following the link at the attached thumbnail image 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 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 if this description doesn't match your canoe. Feel free to reply here if you have any other questions. Good luck with the restoration,
Benson
