Hello.
113589 is a 12' CS (common sense or middle) grade square stern canoe with open spruce gunwales and ash decks, thwarts, and seat frames, a keel and outside stems. It was originally dark green and was shipped with a floor rack to Philadelphia, PA, on February 24, 1936.
113689 is a 16 foot CS grade Yankee model canoe with ash decks, thwarts, and seat frames. It was originally orange and was shipped to Angola, Indiana, on June 28, 1934.
Neither boat had sponsons applied at the factory, and I don't recall Old Town records stating cork sponsons-- the sponsons used on Old Town canoes were constructed of cedar, with canvas covers-- like a small canoe on each side of a larger one. Also, neither is 19 feet long (an unusual size), and the format for Old Town serial numbers has the length of the canoe following the serial number (although the "1" could be the first part of a partly-obliterated serial number). If you post pictures of your canoe, we may be able to identify what you have. Image 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 athttp://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
