Insulating red lacquer behind switch plate

Below you can see where an insulating red colored lacquer was applied to depressions in the switch plate behind the contact mounting screws.  Dale, our resident electrical expert recognized this immediately as a substance called Glyptal.  We were able to buy some as it is still used to insulate coil windings in electrical motors.  As you can see below, there are a few fuses.  The writing is not legible so we'll take a guess.
