Old Town 36593 is an AA (first) grade, 17 foot Otca model canoe finished from February to May of 1915. It has open mahogany gunwales and ash decks, thwarts, and seat frames, was fitted with a keel, outside stems and a floor rack. Original color was dark olive green. It was shipped to St. Albans, VT, on May 15, 1915. Old Town canoes generally have a space after the serial number and then have the length of the canoe but you might find this number is obscured by gunk that can be removed. The number should be on both stems. AA grade canoes usually have mahogany decks/thwarts/seats, so this is different or may have been written down wrong on the record. As you are in Vermont and the canoe seems right in other ways, this may be your canoe. Posting pictures would help too.
