The CDBA is furnished in a heavy aluminum travel chest, shown here on the bench.
		Opening the chest reveals the disassembled rebreather with all accessories.
		All components are protected in padded partitions. Here are the twin main gas cylinders.
		A set of lead balls is provided in cutout holders in the chest. These are for the divers integrated weighting system.
		The counterlung is a molded rubber assembly, also carrying the scrubber, exhaust valves, and the mounting pocket for the bailout system.
		To the scrubber is attached a single breathing hose, a full-face mask, and a dive/surface valve (DSV).
		The DSV has two positions. One allows breathing through the scrubber, the other allows a dressed diver to breath atmospheric air while performing pre-dive checks.
		The FFM has an internal bite mouthpiece to reduce dead-space and C02 buildup.
		The bottom of the front vest carries two small bailout cylinders, described separately.
		Stripped of all components, the counterlung assembly is seen as the fully integrated front half of the rig that is is.
		The counterlung includes a high quality  exhaust valve with manual dump knob.
		The bottom of the front vest contains the bailout gas supply, described separately.
		The adjustable bailout gas control valve  is located at the top right side of the counterlung.

		Additional detail of the front vest with attached components.
		And lastly with the full-face mask connected.
		The front half of the vest and the rear half are connected by bronze buckles, locked in place by a length of rubberized webbing.
		Detail of the right shoulder buckle.
		Buckle placed into position for locking.
		Buckle locked.
		This is the rubber rear-half of the integrated vest and chassis of the rig. The assembly on the right is the integrated weighting system.
		To the vest will be attached all of the other components of the rebreather. Here we can see the main gas bottles which lay across the divers lower back.
		The integrated weight system is very interesting, and deserves detailed study.
		Pulling the very parachute ripcord-like ring at the bottom of the rig would be the method used to jettison weights.
		Doing so would allow a spring-loaded assembly in the middle of the weight pocket to release, thus opening up the flaps of the weight pocket.
		The weight pocket is loaded with lead balls, each weighing about a pound.
		A detail view, with the ripcord located at the divers right hip.
		They system of locking the flaps is intricate to say the least. The system is highly engineered, and was an impressive display of attention to detail exhibited by the designers of this equipment.
		Detail of the weight pocket closed and ready to dive.
		This photograph shows the rear half of the integrated vest assembled with the weight pocket and cylinders, with gas control manifold and the hose that will later be connected to the counterlung for gas injection.
		And finally the front half and the rear half of the assembly is shown on the bench, ready to be donned by the diver.
