Antique Left Hand Door Wishbone Lock- Keyhole Pattern U.K. ca. 1750-1790

This early antique wishbone lock, crafted for a left-hand door, was found in England. This is the first step away from thumb latch technology. A spindle that connects the two knobs passes through a cam mounted in the plate, whereby any rotational motion of a knob is translated to vertical motion of the latch bar.

The components for these platelocks are typically mounted on a square plate, which makes the locks very portable. However, this rare piece features a keyhole-shaped plate.

The plate is 7 1/8" wide and 4 1/2" tall, and the keeper is recently made.

Although tiny Georgian brass knobs are available and correct ($70/pr) when paired with a recently made Georgian-style rosette ($30), any combination of knobs and exterior trims can be used. Shop for "Parts and Components" in the Three Centuries of Hardware dropdown menu.
