OK, not really an exposure meter in the modern sense, but a meter to measure light in foot candles. The patent number is from March 6, 1928 so this dates it to just after that. The meter works has 3 settings of High, Medium and Low. The sensor is hinged so you can point it in the direction you want to get measured. The description and scale is listed on the inside cover. It states "This instrument indicates the illumination in foot-candles based on the international candle on the surface of the light target. It is standardized on tungsten light at a color temperature of 2700 degrees K".

The directions for use are also printed on the case. The meter has a nice hinged door for protection and a leather handle for carrying. It weighs around 2 pounds and is about 7" by 3 " by 2".
