Description

From the seller
This is a Leeds & Northrup Cat. No. 4340. All controls move smoothly, binding posts are intact, and the internal resistance network shows continuity on all tested positions. The instrument appears in good overall shape, with wear from age. Ideal for display, collection, or demonstration of classic laboratory measurement equipment. Does have tag possibly indicating it was repaired or recalibrated by Leeds & Northrup Company. Missing one knob as shown in photos. Please look at all photos for details.
