So a snorkel-mask retained on the head by a harness. One breathing tube emerging via a flexible hose from the mask centre top. A ball valve admits and shuts off the air supply. The model lasted until 1964.
This design bore a passing resemblance to the contemporaneous French-made Hurricane Automatic:
Next time, at the weekend, we shall take a look at the Nemrod Tarzán and Haiti snorkel-masks. Keep well, safe and warm until then.
