AI-assisted summary

Description from the seller

Marking “Carl Zeiss Berlin”
→ used after World War II, especially in West Germany

Industrial design
→ molded plastic + screwed-on metal plate
→ typical post-war, not at all 1900 (which would be brass, wood, leather)

Modern metric graduations, very legible.
→ Scientific standardization of the 1950s–1970s

Complete absence of electronics.

No original case, documentation, or graduated-scale card, but the device is complete and precise.
