Clipped corner thumblatch ca. 1740-1840

Classic Norfolk-styled "clipped corner" thumblatch with cast iron handle forged to steel backplate. Note: suitable for a 3/4" thick plank door due to the short (2 3/8" long) tail of the thumbpiece as it passes through the door. For thicker doors, the plain flat latchbar can be exchanged for a latchbar with a lifting knob.
