Serial number 36321815 is a 15 ft cedar canvas canoe. Single thwart. Ribs x53 spaced 1 1/12 " and 1 1/2 wide. End rib 4 wide. Center is tumblehome. Planking is 4 inch wide. Gunnels held with Robertson screws. Decks circular with no ogee. Full keel 1.5 in at the center. Anyone can help ID this gem. I am about to embark in a major restoration. It was purchased second hand in Ottawa back in the early 1960. Possibly a 1950ish build.
