Notes1: The #20 circular plane was acquired from Leonards Bailey's sale of his Victor plane patents and tools in stok in 1884. Stanley's model Type 1 has Edmunds Schades's 2/7/1893 patent date cast into the frame and his 4/19/1892 patent on the cutter. Earlier models will have the model number cast in script lettering on the adjustment knob. Of all the circular planes manufactured by Stanley Rule & Level Company, this is the sturdiest and the model often recommended as the most usable of the circular planes. Type 2 (1907 to 1909) will have the same features as Type 1 (nickel plated, 9-1/2 inch, 2/7/1893 patent date) except the blade will have a "T" style trademark.
