The "All Knowing Serial No. Folks" aren't available so hopefully you can make do with those of us who have access to a few records. The Old Town canoe with serial number 17241 is a 16 foot long, CS (common sense or middle) grade Charles River model with red western cedar planking, closed spruce gunwales, hard wood decks, ash thwarts, ash seats, a keel, and a painter ring. It was built between March and May, 1911. The original exterior paint color was dark green. It was shipped on May(?) 19th, 1911 to Saint Paul, Minn. 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 others 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/ot_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
http://www.wcha.org/about-the-wcha/ to learn more about the WCHA and
http://store.wcha.org/WCHA-New-Membership.html to join.
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,
