Downeast Maine Boat Builders Antique Handmade Angle MeasureOf course found in Maine, and I know pulled out of an old boat builder's shop in Ellsworth, near Bar Harbor. I know little about the art of boat building, but sure do love a handmade tool, and clearly this was used for marking angles, I presume in a similar way to a bevel gauge. I love it as an object, with to my eye great beauty to all those graphite drawn lines, and I especially love the the knot in the wood on the left edge toward the bottom,
