This is a very very rare pure oxygen rebreather. The Pirelli rebreathers were made famous by the Italians in WW2. 

Oxygen Tanks are aluminium. Date code is in the 1960's.

I was told that this unit was never dived!

Selling as a collectible for display only although all parts are present and appear to be in good working order.

These units were used by US special forces in the 50's and 60's.

The manual for this unit is available at:
