It would be good to have a picture of the whole canoe. 109781 is apparently the correct length (17'), but is a mahogany trimmed Otca and would have the long Otca decks with coaming... I'll post the information on this canoe, so you can compare:
Old Town 109781 is a 17 foot AA (top) grade Otca model canoe, finished April-December of 1931. It has red Western cedar planking, open mahogany gunwales and mahogany decks, thwarts, and seat frames. It also has a keel, outside stems, and a floor rack. It was originally painted design #34 and had the name "Thebob" in white on the right side of bow and stern (at least I think that's what the notation means). Shipped December 21, 1931, to LeRoy, New York.
I'll attach this build record so you can compare with what you have... this canoe would be considerably different from the HW model, especially with outside stems... this was maybe a tricked-out Christmas present for some lucky person during the Great Depression. The canoe was shipped with paddles.
Note where the canoes were shipped and if that makes any sense when considering where you found it.
I'm attaching images of the Old Town designs from the 1931 catalog from "The Complete Old Town Canoe Company Catalog Collection, 1901- 1993", available on CD from
http://www.wcha.org/catalog/ and
http://www.dragonflycanoe.com/cdrom.htm on the web.
Design #34 is in the lower right corner-- the red canoe with white stripe. If the canvas on your canoe is original, some archeology may tell you if this is the right record.
NOTE: The attachments won't attach--- some web-problem I assume, but I'll send this now and attach them later.
