Vintage Aqua Lung Regulator. One of the first regulators to carry the Aqua-Lung label. Two-stage, unbalanced upstream regulator without a venturi assist. The DY Aqualung and DA Navy approved are mechanically identical.The DY Aqualung featured a one-piece hose without check valves, while the DA Navy-approved featured the then-new three-piece hose with check valves to prevent the regulator from becoming flooded. They are fairly difficult to tune regulators with a strong work of breathing. Untested, as-is.
