My latest purchase was an OT Yankee ca 1952, 156997 16. A copy of the build sheet would be nice, so thanks to you guys that can provide a copy. As for condition, there are 8 broken ribs, some tender areas of planking and the tips are just tender, the stern deck is broken. That can be aligned, glued and reinforced with an inlayed butterfly underneath for extra strength. That is not an sect like inlay but sort of a double triangle look "point to point", see Nakashima furniture to get a better understanding. New bent ribs and planking purchased in 1974 came with it as did 17 ft of #8 canvas. I think I will save the canvas for something else and get some #10 or possible #12 and go toward the lighter side of things. It has copper bang strips that meet up with aliminum along the keel. Seat bolts and all screws for the outer rails were missing.
