The Old Town canoe with serial number 83270 is an 18 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, a floor rack, and sponsons. It was built between February, 1924 and June, 1925. The original exterior paint color was Yale blue enamel. It shipped on June 22nd, 1925 to Kalamazoo, Michigan. 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 as you probably know well. 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 if this description doesn't match the canoe. Feel free to reply here if you have any other questions.
