B66-656 PLOW PLANE. Silcock Type. Strongly resembles the James Silcock's patent, the earliest patented metal plow, but unmarked and with significant differences. Brass body with 7" iron skate, rosewood fence with iron plate. The cutter holder is very different from the Silcock patent, with a brass collar. Possibly the work of a talented craftsman, or maybe a previously unidentified patent. Good+ 300-600
