A characterful piece of scientific and industrial heritage: an analog voltmeter with a curved 0–40 V scale and the inscription “Albert van der Perk Rotterdam.” The original manufacturer has not been established.
According to the seller, the meter dates to approximately 1950–1955. This date has not been independently confirmed.
The deep-black housing, described by the seller as bakelite/phenolic resin, contrasts beautifully with the light-colored dial. Two insulated terminal knobs sit on top. Its restrained lines make it an appealing collectible for enthusiasts of historical measuring instruments, industrial design, and Dark Academia interiors.
