B66-542 BLOCK PLANE. Gage Patent. In 1913, some 30 years after he patented the self-setting mechanism that launched the Gage Tool Company and subsequently the Stanley line of Gage planes, John Porcius Gage took to his workshop again to improve the block plane. The result was not a success - when Stanley bought the company three years later it had no particular interest in the 1913 patent - and examples are extremely rare. There is one other example in Figure 137 of PTAMPIA I. This one more closely resembles the patent drawings, with a low angle cutter and wide flat knob. It isn't marked, and could be a prototype. Japanning 95%, very clean, and possibly unique. Fine 1000-2000
