• Design: The unit includes a rectangular viewing window that reveals the internal mirror and coil mechanism. The top of the cylinder typically features a "Zero Adjuster" and "Coil Clamp" for fine-tuning measurements.
• Era: These instruments were widely used in physics laboratories and research facilities during the early-to-mid 20th century, particularly around the 1920s.
• Condition: [Insert personal observation: e.g., "The black enamel finish shows minor age-appropriate wear," or "The internal mirror appears intact."] Please note this item is being sold as a collectible scientific instrument; functional accuracy has not been tested.
• Dimensions: Approximately 9 inches (22.8 cm) in height and 5 inches (12.7 cm) in diameter.

Historical Significance:
Leeds & Northrup were pioneers in precision electrical measurement. This specific type of "moving-coil" galvanometer was essential for bridge measurements and other sensitive electrical experiments in its time. It makes an exceptional display piece for collectors of vintage electronics, steampunk decor, or scientific history.
