• Lot Description

  The US Navy Mark V is arguably the most iconic helmet design ever made. Its style and history have made it one of the most popular helmets among collectors worldwide. The model was made for the US Navy from 1916 till the mid-1980s.
  
  During the entire production run of the Mark V, there have only been 4 manufacturers. Three of those makers made the Mark V in relatively large numbers throughout the 20th Century. The one company that would only make the Mark V from 1943 to 1944 was Miller Dunn. Examples of the Mark V from this company are considered by far the most difficult to locate. With a production run of only 1200 to 1500 helmets, the Miller Dunn Mark V is the rare one!
  
  Miller Dunn was located in Miami, FL. Starting in 1916 the company would make the Divinhood. This helmet was a shallow-water model that the US Navy would go on to use. From 1916 to the end of World War 2, Miller Dunn would produce the Divinhood, evolving from the 1st model to their Style 3 Divinhood – also used by the US Navy. This experience in helmet manufacturing and relationship with the US Government undoubtedly led to a brief contract to produce to the Mark V helmet.
  
  This helmet was made on September 1st, 1944. This information is on the lead Mark V ID plate. Per government specifications, all Mark V helmets were to be dated with at least the month and year it was produced. In addition to the date, the helmets serial number is also stamped on the ID plate. Miller Dunn elected to use a lead ID plate, which resulted in many of their ID plates being marked or worn down easily, leading to helmet information being difficult to read. This specific ID plate has survived in relatively good condition.
  
  In addition to the date of manufacturer, Miller Dunn Mark V helmets feature a serial number, in this case, 915. Miller Dunn would also stamp the serial number on the inside of all four brails and the inside of both neck rings. This helmet we are pleased to report, has all the remaining brails and both neck rings with the same matching serial number! This is absolute proof the helmet has been together since it left the Miami, FL factory in 1944.
  
  The photos show this helmet with the bonnet and breastplate not threaded together. One of the neck rings appears to be slightly out of round, currently preventing a proper mating of the two parts. The helmet does offer a fantastic original patina with a majority of the factory applied tinning remaining. There are twelve wing nuts intact, five flange style, and seven standards. There are three brails present, all of which have the matching 915 serial number.
  
  On the inside of the helmet bonnet, the original air vents are present, communications line clips, as well as the exhaust button. The window guards, glass, air fitting elbow, BTE exhaust, spitcock valve, communications elbow, and dumbbell safety latch. The safety latch chain and cotter pin are missing. The original neck ring gasket is long gone. There is a Schrader stamped non-return valve. The communications elbow has a brass cap threaded on it. The top of the bonnet exhibits only a few minor working dents from use.
  
  All diving helmets in this auction will be accompanied by a certificate of authenticity from Nations Attic. The certificate will have a unique number that will match the number on a tamperproof hologram decal placed inside the helmet. This information will be kept on permanent file at Nations Attic and help ensure the provenance of the helmet and authenticity. The display stand shown in the photos is not included. The option to purchase one after the auction will be provided.
