€150,00 EUR
A distinctive piece of mid-century European scientific heritage: a modular laboratory projection meter, described by the seller as an early-1950s instrument made by E. Leybold's Nachfolger in Köln-Rhein, Germany. The deep-black housing, identified by the seller as bakelite, gives this physics instrument a striking, minimalist industrial appearance. Its dial features two scales marked 0–30 V and 0–12 A. According to the supplied description, this meter belongs to a modular projection system with an internal mirror arrangement. With a suitable light source, instruments of this kind allowed professors to display measurements to students in a lecture hall. The seller also reports a deeply engraved original maker's mark and calibration matrix; these details cannot be verified from the supplied photographs. A characterful collectible for enthusiasts of historical physics, scientific instruments, and mid-century industrial design. Details: • Attributed manufacturer: E.
