Welcome and congratulations, the Old Town canoe with serial number 80623 is a 17 foot long, CS (common sense or middle) grade, HW model with red Western cedar planking, open spruce gunwales, birch decks, birch thwarts, birch, seats, and a keel. It was built between October, 1923 and May, 1924. The original exterior paint color was dark red with a quarter inch gold stripe and Greek ends. This may have been similar to the design shown at
http://www.wcha.org/catalogs/old-town/designs/design37.gif which was later known as their design number 37. It shipped on May 13th, 1924 to Fairlee, Vermont. A scan showing 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. Please provide a picture if the original design is still showing. Feel free to reply here if you have any other questions.
