Weston Model Model E.703 Lightometer F*S
Here is a perfectly functioning 80 year old light meter!
The Weston Model E.703 is a Lightometer rather than an exposure meter as such. It reads light values (foot candles) but there is no mechanism to convert them to exposure settings using shutter speeds, apertures and file speeds. This neat little unit measures 4 5/8" high by 2 5/8" wide with a depth of 1 7/16" and weights in at 12 ounces. This meter is flawless, you can see the Weston logo on the original selenium cell in the last image.
