The original specs on these meters were quite impressive for the 1920s — at the time they were considered laboratory grade and specified at 0.5% accuracy. With their mirrored 150-part scales and balanced, sharp index needles, it was quite possible to take readings to at least 0.5 V resolution on the 150 V scale (would we call that a 2¾ digit instrument today? 9 bits, anyway.) . This is in great condition! A different version of the other one posted here.
