Description: |
| The wrench has a spring nut-retainer in the box end, and the drawing shows an "alligator wrench" end, internal wrench openings, and a circular "finger hole" to rapidly spin the axle nut.
Produced as the "IDEAL" and with the names of buggy and implement manufacturers cast in the shank. Instead of the alligator jaw, these have three open end sizes. |
