It is a 20.000 Ohm/Volt DC meter. So suitable for tube radio/tv repairs. On old schematics is mostly mentioned with what type of meter the voltages mentioned in the diagram, are measured. This to avoid wrong measurement.
The interior. Custom made switch, all moulded in Bakelite. Left: battery compartment for D-cell and on the right: 30 V battery.
Switch, seen from the side. The resistors lie in a sort of place holder.
The Novel BL020 battery gave 30 V.
