Hi Dave,
63804 appears on a 17' Old Town Otca in AA grade with 20" mahogany decks, seats, thwarts and gunwales. This boat also had outside stems and a keel. The color is a bit unclear - seems to read "Maritime" although I could convince myself it is "Maroon". It was shipped to Chicago, IL in March of 1921. Build record is attached.
Was great seeing you at Assembly again this year. Hope your trip home was uneventful.
Mike
