Summary
Replace with: High voltage high vacuum half wave rectifier, used in an oscilloscope manufactured by Loewe Radio in 1939. 2 volt directly heated cathode.
The last zero in the type number has presumably been rubbed off. It probably had a European style 4 pin base although the plain cylindrical top cap suggests that it might have been an NG3020A in which case it would have had an 8 contact side contact base. Closer inspection might clarify this.
Manufacturer: Loewe Radio A.G., Berlin, Germany.
Physical Description
Base type: no base but 2 wires coming out Bulb shape: conical Bulb material: glass Top cap
