Re: AVO Multimeter survey
Phil,
The serial number is certainly consistent with a 20 Range AVO from February 1937.
(AVO never called "Model 3", although that's what it was).
If it is a Model 3, it should have 12-based voltage & current ranges,
and four resistance ranges (1K, 10K, 100K & 1M)
only the lower two of which work on the internal battery.
