It's great to have a "family canoe"-- please share pictures.
Old Town 131481 is a 17 foot AA (top) grade Otca model canoe that was completed January--> April of 1941. It has open mahogany gunwales and mahogany decks/thwarts/seat frames, a keel with full-length bang plate, additional bilge keels, and a floor rack. Originally, it was painted garnet red. it was shipped to a fellow named Sam in Royal Oak, MI, on April 28, 1941-- not long before WWII.
I'll attach images from the 1941 catalog, courtesy of "The Complete Old Town Canoe Company Catalog Collection, 1901- 1993", available on CD from

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 and anyone else reading this will join or renew membership in 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. Feel free to reply here if you have any other questions.
More information on the Old Town Company can be found in Sue Audette's book, "Old Town, Our First Hundred Years", which is available through the WCHA store and most booksellers, eBay, Amazon, and public libraries.
If you have any specific questions about your canoe-- restoration questions, where to paddle, etc. -- please ask.
