Some pictures of the serial numbers may help since none of these numbers match. My guess is that you really have the Old Town canoes with numbers 122884 and 99947.
The Old Town canoe with serial number 122884 is an 18 foot long, AA (or top) grade, HW (heavy water) model with open mahogany gunwales, mahogany decks, mahogany thwarts, mahogany seats, a keel, and a floor rack. It was built between September, 1937 and July, 1938. The original exterior paint color was dark green. It shipped on June 24th, 1939(?) to Hampton, Conn.
The Old Town canoe with serial number 99947 is a 17 foot long, CS (Common Sense or middle) grade, HW (heavy water) model with red western cedar planking, open spruce gunwales, ash decks, ash thwarts, ash seats, and a keel. It was built between November, 1928 and June, 1929. The original exterior paint color was dark green. It shipped on June 22nd, 1929 to Hartford, Conn. It was returned for repairs on May 24th, 1949 from East Hartford, Conn as shown on the back side.
Scans showing both of these build records can be found by following the links at the attached thumbnail images below. These scans 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 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 renew.
It is also possible that you could have another number or manufacturer if these descriptions don't match your canoes. Feel free to reply here if you have any other questions.
