Congratulations, the Old Town canoe with serial number 134479 is a 17 foot long, CS (Common Sense or middle) grade, HW (heavy water) model with open spruce gunwales, ash decks, ash thwarts, ash seats, half ribs, a keel, sponsons, and a painter ring through the bow stem. It was built between December, 1941 and July, 1942. The original exterior paint color was dark green. It shipped on August 5th, 1942 to Baltimore, Maryland.

 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 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.  A similar canoe is shown  at
