Snead & Co produced this type of shallow water diving hat during the first half of the 20th century. Although some were produced in brass, the expense involved led to the majority being made from cast iron. Later copies have also been produced, and are said to be distinguised by not emplying an American thread for the pipe connections. This example was apparently sold with other unwanted items on a quay in Cornwall during the 1940's by a U.S. vessel and has been kept in Jersey (Channel Islands) until now.
