Vintage Triplet Milliamp on Stand Item # F5986

Circa 1934


Founded in Bluffton, Ohio in 1904 by R.L. Triplet, Triplet still makes milliamp readers today as part of Jewel Instrument's family of manufacturers. This handsome devil, Model 321, was patented by R.L. Triplet in 1934 with the goal of further advancing their line of electrical range measuring tools. While the practical history is interested, we are just as captivated by the textured black finish, the red and green jewel indicators and the wonderfully tapered cast base. A great piece of industrial history.

  • Historical Style: Industrial
  • Condition notes: Excellent condition, although the mechanism is untested.
