B68-359 INFILL SHOULDER PLANE. J. Popping. Cast iron shoulder plane by Joseph Popping, one of the rare US makers of infills, who were clustered in New York in the late 1800s. The cutter, rather than the body, is marked, which was typical, but the design is consistent with other Popping planes and identical to PTAMPIA II Figure 301a. 6-5/8" sole, 1" iron, rosewood infill. Wood has light wear, metal oxidized with some tiny chips along the sole and small casting flaw on heel; otherwise a good clean example. Good+ 150-300
