    • Kevin M. (4/2/2020)
      Just found a pair of these in my fathers machinist chest, they must be 50 - 60 years old at least. He was a machinist at the Allison aircraft engine plant in Indianapolis during WW 2 working on tooling for the P51 Mustang engine before they went to the Merlin engine. He was drafted after that and after the war worked as a machinist off and on for several years.
