Arguably the most popular and iconic diving helmet ever made is the US Navy Mark V. Finding one that was used during World War 2 and then put away, retaining the same condition & look, is a rare treat. This wonderful 100% authentic Mark V was made during August 1943 by the A. Schraders Son Company in Brooklyn, NY. The helmet retains a hint of its original gray tinning along with an unmistakable green patina from use in saltwater many decades ago. The helmet is complete with all four serial # matching brails, 12 wing nuts, window glass and guards. The internal air vents and exhaust button are present as well. The communications cup does have a US Navy inspection stamp Â– proving this helmet was in US Navy inventory! There is a red painted 3 on both the bonnet and breastplate. As is the case with Schrader Mark Vs from World War II, not all of them have a serial # on the communications cup. Schrader would put a # on the inside neck ring of the bonnet which was not associated with the helmet serial #. There is no doubt however that this example is all original and matching just as it came from the Schrader factory at the height of WWII. Helmet will be accompanied by a numbered certificate of authenticity detailing its history. A matching serial numbered hologram decal on the inside of the helmet from Nations Attic will be applied as well to preserve the helmets history and authenticity. The display stand shown in the photos is not included. The option to purchase one after the auction will be provided.
