Description: |
| The movable jaw fits in a slot in the main shank. The adjustment collar and finial end nut are held in place by the set screw in the inner retaining collar.
This piece would have a substantial number of small parts requiring significant machine work. It was conceived as a wrench that could be adjusted in confined spaces. |
