East germany oxygen rebreather "Medi Nixe"

The legendary "Medi Nixe" from (Medi)medical industries Leipzig. The first and only industrially produced in the GDR oxygen rebreather for sports divers. It was produced from about 1954 - 1959/60 . Then stop the production was because of alleged dangers of oxygen diving, but rather because of the potential "escape risk" .

Many thanks to Dieter Florian,dive shop on dive base at the lake "Kulki", , he demonstrates me this fantastic device.
