all old diving gear, this is being sold for DISPLAY ONLY. It should not be dived without having passed inspection by
a certified dive shop. The

MK V DEEP SEA DIVING DRESS: By 1915, the Bureau of Construction and Repair had designed
the MK V Diving Helmet which seemed to address many of the problems encountered in diving. This deep-sea outfit was designed
for extensive, rugged diving work and provided the diver maximum physical protection and some maneuverability. The 1915 MK V Diving Helmet had an elbow inlet with a safety
valve that allowed air to enter the helmet, but not to escape back up the umbilical if the air supply were interrupted. Air
was expelled from the helmet through an exhaust valve on the right side, below the port. The exhaust valve was vented toward
the rear of the helmet to prevent escaping bubbles from interfering with the diver’s field of vision.By 1916, several improvements had been made to the helmet, including
a rudimentary communications system via a telephone cable and a regulating valve operated by an interior push button. The
regulating valve allowed some control of the atmospheric pressure. A supplementary relief valve, known as the spitcock, was
added to the left side of the helmet. A safety catch was also incorporated to keep the helmet attached to the breast plate.
The exhaust valve and the communications system were improved by 1927, and the weight of the helmet was decreased to be more
comfortable for the diver. After 1927, the MK V changed very little. It remained basically
the same helmet used in salvage operations of the USS S-51 and USS S-4 in the mid-1920s. With its associated deep-sea dress
and umbilical, the MK V was used for all submarine rescue and salvage work undertaken in peacetime and practically all salvage
work undertaken during World War II. The MK V Diving Helmet was the standard U.S. Navy diving equipment until succeeded by
the MK 12 Surface-Supplied Diving helmet in February 1980, which in turn was replaced by the MK 21 in December 1993.
