B66-613 COFFIN PLANE. E.W. Carpenter Patent. Good example of Carpenter's March 27, 1849, patent, which used two wedges with the cutter held between them. We've seen this in jointers and occasionally a jack plane, but this is the first coffin smoother we've seen. 8-1/2" sole, 2-1/2" Humphreysville cutter, spalled. B mark that includes the patent date (upside down), four stars in AWP. Wood is oxidized with one significant check in the heel and a few small scrapes and dings. Good+ 150-300
