Description: |
| The patent shows a sliding latch to hold the adjustment of the movable jaw. The wrench marked with this patent number does not have the latch. This wrench, like the known example of Ersland's April 1, 1930 patent (no. 1,752,425), appears to have been assembled by hand, and is marked with a stamping applied one letter at a time. |
