Vintage Plomb WF-35 1/2″ Drive Socket Extension 9 5/8″

The Plomb Tool Company was an important and innovative maker of automotive hand tools during the first half of the 20th century, growing from a modest blacksmith shop to become one of the largest producers of hand tools. Then through an odd problem with trademarks, Plomb had to change its brand name to "Proto" in 1948, leaving a legacy of Plomb-marked tools as a snapshot of early to mid-20th century tool production.
