Stanley #18 knuckle-joint block plane, Type 5.

Description

Better than average block plane with knuckle-joint lever cap and adjustable throat.  These are very comfortable to use (the major advantage of the knuckle-type cap).  Lever cap works well and shows no signs of stress. Adjustable throat works smoothly.  Finishes are what you’d expect on a plane that’s more than a century old, but quite serviceable.
