Randy, I have an M-10 and the hull looks identical to yours. The interior is different...side seats go forward to a moulded center seat made just like the sides. The seats are sealed and the boat floats if flooded. The breasthook and side rub rails look the same. The transom has wood across side to side which makes way for a small wood motor mount. Mast is set in a wood cross brace about 2' aft of bow. All the wood is teak. I suppose they made several different interiors...got this one sometime around 1975. Bill P.
