7401-171 FULTON patent butt gauge. Deceptively simple and modest in appearance, consisting of two sliding blocks of wood with a locking screw, the Fulton gauge, patented in 1888, is actually a very clever design copied by Stanley in the No. 95. The original Fulton model is hard to find. As usual, missing the third scoring point which was not attached. Good (NPO900) 40-80
