The Old Town canoe with serial number 21560 is a 16 foot long, AA (or top) grade, Charles River model with red Western cedar planking, open mahogany gunwales, mahogany decks, mahogany thwarts, mahogany seats, half ribs, open mahogany finish (outside) rails and a keel. It was built between March and May, 1912. The original exterior paint color was dark green. It shipped on May 22nd, 1912 to Lambertville, New Jersey. A scan of this build record can be found by following the link behind the attached thumbnail image below.
These scans and several hundred thousand others 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/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

It is also possible that you could have another number or manufacturer if this description doesn't match your canoe. This is a bit early for diamond headed bolts so those may have been added in a later repair. Feel free to reply here if you have any other questions. Good luck with the restoration,
