H. Chapin Union Factory BoxWood Plow Plane Antique Mid 1800's Rare. All original gorgeous plane. Stealing great working condition with a sharp and healthy blade. The only flaw that I see is one wing is missing from the wing nut. What an addition this would make two any collection. Attached pictures shows the plane opened up to right at 4 inches. It will open up a little more. Plane measures 9 3/8 inches long. It stands right at 3 1/4 inches tall and of course it is adjustable to where you set your fence. All the way closed, it measures just over 3 inches wide.
