The Walden Worcester Ratchet is a little Plumb/Proto like, and a little New Brittan like.
The first thing that is odd is, it has screws in both sides.
You want to take the 2 furthest from the handle out first.
The poor ratchet below also shows the weakness of this design, all the force on the pawl is focused at the screw, when forced, the thin end of the pawl breaks and the pawl jumps out of place and i t's all over...
