Anyone have any more info on this one? GenRad or General Radio made test equipment. According to Wikipedia they started in 1915.

"Among General Radio's accomplishments over the years have been:

* The introduction of one of the world's first portable oscilloscopes
* The production of many high-precision standards for resistance and capacitance
* The commercial production of the stroboscope as the Strobotac
* The commercial production of the sound level meter
* Commercial invention of the binding post.
* Invention of the GR connector
* The Variac variable autotransformer"

According to the General Radio Historical Society, they made the first commercial oscilloscope:
"In 1931 there were several ways of observing electrical waveforms. One was to apply different signals to the deflection plates of a cathode-ray tube. Such tubes were available at the time and used by many experimenters. General Radio provided the first commercial version of such a device in 1931 with tubes, first from Germany, and later from Westinghouse, U.S. The instrument was in two pieces with the tube mounted on a stand and the power supply in a separate cabinet."
