Clough-Brengle Oscillograph

And here we have yet another restoration project, caught right before I started. This victi--err--patient is a Clough-Brengle model CRA Cathode Ray Oscillograph. It was manufactured in Chicago around 1935, and was first available for around $80.

 

Originally the faceplate would have been silver colored, but age and possibly sunlight has caused the lacquer to assume an elderly golden glow. A metal shade would have fitted over the 3" round cathode ray tube to shield it from ambient light, but that piece is missing.
