Vintage 1960s Rex 300 White Plastic Light Exposure Meter

This is a very nice Vintage 1960s Rex 300 White Plastic Light Exposure Meter.

Although in working condition, I'm not sure how accurate it is as it's many years since regularly used. Made from cream-white plastic, with red and gold accents, it has a long red cord to enable it to be hung around the neck. 

The exposure meter is in very good condition, slightly scuffed and marked; commensurate with age and use.  The selenium cell is covered with a colourless plastic slide which fits neatly in a groove on the back of the meter when the meter is in use.

Approximate measurements (Exposure meter ) WHD: 5.5 x 7.0 x 2.5 cm

Dating to the early 1960s, Made by Rex, West Germany.

A great little gizmo to use with your vintage cameras
