Old Town 146808 is a 16 foot CS (common sense or middle) grade HW model canoe that was completed October-December of 1946. It has spruce planking (planking is usually cedar and most often is red Western cedar), open spruce gunwales, ash decks, ash thwarts, and ash seat frames. The seats are caned.
During the war, the supply of cane was exhausted and canoe builders devised different methods of building a lightweight seat. Old Town used slatted seats, and this replacement isn't always noted on build records. It's interesting to know that the cane supply was back by late '46... I figured it was sometime in '47.
Your canoe has a keel and was originally dark red. It was shipped to Kaufmann's in Pittsburgh, PA, on March 18, 1947. A copy of the scan of this record is attached below... click on it to get a larger image.
This scan 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 http://www.wcha.org/wcha/ to learn more about the WCHA and http://www.wcha.org/join.php 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.
