Description: |
| The wrench handle is the body of the pump; there is provision for storage and insertion of screwdriver blades. The wrench serves as the handle for the pump, and can be uncoupled and used independently. There is an option for inclusion of an oiler.
A known example has no visible markings and does not include an oiler or other auxiliary tools. It does have a swinging latch to hold the outside of the pump barrel firmly to the jaw when used as a wrench. |
