The aluminum slide rule at right has me completely baffled. It’s not, strictly speaking, a slide rule at all — there’s a stator and a cursor, but no slide. It resembles the simple measurment conversion rules one sometimes sees. However, while some the scales are linear, a few are not — and the labels on the scales (Nm, Td, Neb, Nel) don’t ring any bells with me at all. The company still exists, manufacturing a wide range of equipment, especially biology instruments and scales.

If you have any knowledge of this slide rule, or can make a good guess, please leave a comment here.
