The Draeger Norge II (article no Draegerwerk T5650) is an Oxygen Closed Circuit rebreather.

The Lt Lund II is the successor of the Lt Lund I and the model 138, the latter was the classical Baracuda tauchgeräte that Hans Hass used in the 1940's. According to G. Haux "Tauchtechnik" the Lt Lund was developed 1953 - 54 in collaboration with the Norweigan Navy and Leutnant Lund. 

The main improvements made to the Norge (as compared to the Lund II) were:

·         Larger (3.8 L) sorb canister

·         Larger diameter breathing hoses

·         Larger diameter non-return valves placed in the DSV

·         The pressure gauge is mounted directly on the manometer

The Norge unit comes in an early version , the Norge I, with a canvas breathing bag and a later, Norge II, (shown below) with a fabric reinforced rubber breathing bag.
