Congratulations, the Old Town canoe with serial number 83726 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 outside stems. It was built between February and March, 1924. The original exterior paint color was bright red. It was shipped on May 19th, 1924 to Long Island City, New York. 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 your canoe. Feel free to reply here if you have any other questions. Good luck with the restoration,
Benson
