B66-608 UNHANDLED SCREW-ARM PLOW. J & L. Denison. Solid boxwood throughout. A couple of small chips from the threads, tight check in front shoulder, and a couple of other minor dings but overall a very clean and attractive boxwood plow. Brothers John and Lester Denison made planes in partnership in the 1830s; John continued in business until 1876 but plows marked by the partnership are uncommon. B mark, without the upper and lower decorations. From the collection of David Jeffers. Fine 200-400
