The VP2 is a battery variable-mu amplifier HF pentode dating from the early 1930s. When originally introduced the anode top cap was Bakelite and featured a screw down fixing. See SD20 for style. This exhibit has a modern top cap and is clearly of later manufacture, probably for replacement use.
The classic envelope is 45 mm in diameter and, excluding the B7 base pins, is 110 mm tall.
