Pendulum rebreather PT1

I had once again a desire to glue something. An army rubber bag, with from both sides rubberized fabric, stood as a material dispenser available. The fabric is very strong, so I build the unit without an extra cover. The result is a very compact pendulum rebreather, in the style of the old italian pirelli pendulum rebreather. This time I show the construction without pictures and show only the finished product..
