The US Navy Mark V diving helmet was made by A.J. Morse & Son Inc of Boston from 1916 until the 1950s. The plaque on the helmet is dated in 1916 and caries the serial number: 2212. The bonnet (top part) was attached to the breastplate by a threaded collar. The bonnet and breastplate were copper and most of the other fittings were brass.
