Gerry,
While we’re at it, here is a “before” picture of my Stromberg Carlson 694 with the marble still glued to the tuning eye hole in the dial. Somebody had flattened the glass on the business end (I’m guessing with a belt sander), apparently to match the top of the 6U5. Perhaps the tube’s phosphor had gotten dim and the genius thought this would make it look brighter.
