GLOM acquisition

Got some new old GLOM yesterday, type VA50S, VS50S, and VS67S photocells.

VS50 "sensibly equivalent" to 90CV
90CV @ The National Valve Museum

VA50 "sensibly equivalent" to 90AV

No datasheet found for VS67 as yet.



Also a DC Millivolt source used for calibrating instruments



Found this video on the unit

As well as this thing which appears to have 1907 and someone's initials carved on the inside cover, which measures +/-70 something that no one knows what. The needle is broken but according to my father it was intact not long ago so I guess it must have bounced off or something during transport. Looks like it can be fixed.
