Was the 37-116 standard model the only model to use these features together? The last shadowgraph was in '37 it was dropped for the '38 models right?

Hi Terry

The 37-675 Standard also used a shadowmeter and Magnetic Tuning, but no automatic tuning mechanism.

There were some 1938 models that used a shadowmeter. None of these had Magnetic Tuning, though.
