Weston Photometer Model S85 Lux Meter c1961 UK man.
S85 with an alternative meter legend and scale in Lumens per Square Foot in place of Lux. Assuming the meter sensitivity is constant, this indicates that Lux relates to lumens per square foot by a division factor of 10.
The S85 in this instance, set up to read Foot Candles.
This is a rare example of a bespoke S85 meter made for the Benjamin Electrical Company. The E703 meter is frequently found badged for this and other electrical companies, but not so much this model. The name Weston appears nowhere on it.
