The Old Town canoe with serial number 129251 is a 16 foot long, AA grade, HW (Heavy Water) model with open mahogany gunwales, mahogany decks, mahogany trim, a keel, and a floor rack. It was built between February, 1940 and September, 1941. The original exterior paint color was dark green with the name Skipper on the right and left of the bow. It shipped on April 25th, 1941 to Macedonia, Ohio. A scan of this build record can be found by following the link behind the attached thumbnail image below.
This scan was created with substantial grants from the Wooden Canoe Heritage Association (WCHA). Additional information about 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 contribute 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.html to join.
