Midcentury Minox Camera Light Exposure Meter MCM

A midcentury miniature camera light/exposure meter by Minox. Made in Germany, the small meter comes in a red leather case with a metal chain and lanyard. Sold in non-working condition (as I don't know how to use it), the meter has surface scratching and some red marks from case color transfer. Case is intact, but does have a split side seam. see photos. The background of Minox meter is a brief one: introduced in 1951, as a companion to the (then) new model of Minox A, it took the world by surprise: the smallest light meter at only 53/30/18 mm. It was initially manufactured by Gossen, hence the name on the first model, MinoSix (Minox and Sixtus, the then flag meter produced by Gossen). Starting 1954, Minox decided to go their own way and started to manufacture their own meter, getting the needed parts from elsewhere. Production appears to continue after the introduction of the Minox B, around 1960. Usually they were sold only with the companion Minox camera.
