b61-609 THREE ARM PLOW PLANE. D. Kimberly Patent. Good clean example of England's only three-arm plow, patented and manufactured by D. Kimberly & Sons. Unhandled version, wood and metal both very good, including most of the original red paint on the bridle, and has the often-missing wingnut. The Kimberly mark on the toe is faint and partly obscured by a user mark, but the patent number is clear. Fine 150-250
