Welcome and congratulations, the Old Town canoe with serial number 98191 is a 16 foot long, AA (or top) grade, Otca model with western red cedar planking, open mahogany gunwales, twenty inch decks, a keel, and a floor rack. It was built in 1928. The original exterior paint color was white with a half inch gold stripe and turned down ends. This was probably similar to the image at
http://www.wcha.org/catalogs/old-town/designs/design27.gif which was also known as the design number 27. It shipped on June 26th, 1928 to Brantingham Lake, Glenfield, Lewis County, New York. A scan of this build record can be found by following the link at the attached thumbnail image below.
This scan and several hundred thousand more 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/catalogs/old-town/records/ if you want more details. I appreciate that you have just joined 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. A family connection always makes a canoe extra special. Feel free to reply here if you have any other questions.
