B66-660 JOINTER. Birdsill Holly Patent. Holly received his patent in 1852 for the first commercially successful metallic plane. This 20" plane with a smooth sole (the dimpled soles would come later) is unmarked but virtually identical to that shown on page 18 of PTAMPIA II. The tote and wood insert behind the tote are both loose in its dovetailed slot, with a shim, but that's an easy fix, and the wood and metal are otherwise near fine. 2-1/2" Casey Kitchel cutter. Good+ 500-1000
