B66-612 JOINTER. Worrall Patent. Uncommon variation on Thomas Worrall's 1857 patent that used a bolt through the rear of the plane to secure the cutter. Instead of having a full cast iron plate, it has a partial iron top with a socket for the tote. Like the fore plane in Figure 27a on page 29 of PTAMPIA I, with a 22" sole and no knob. Lowell Plane & Tool Co. B mark on toe. 2-3/8" William Ash cutter, which were used by other Lowell planes and is probably original. Wood has light overall wear but no damage, iron top plate has lost its yellow japanning. Good 80-160
