Welcome and congratulations, the Old Town canoe with serial number 24021 is 15 feet long so that isn't a good match. My guess is that you actually have the one with serial number 124021. This is a 16 foot long, CS (common sense or middle) grade, Yankee model with open spruce gunwales, ash decks, ash thwarts, ash seats, and a keel. It was built between December, 1937 and May, 1938. The original exterior paint color was dark green. It shipped on May 18th, 1938 to Cleveland, Ohio. 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 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
