Duplicate of the original 1948 US Navy “Hull Standard Plan” for the Navy Standard Diving Helmet. In layman’s terms, this is the blueprint drawing the United States Navy had on file for the specifics of the Mark V diving helmet. If a manufacturer such as Schrader needed specific details of any aspect of the Mark V helmet, this is the blueprint the Navy would supply to them.
This high-quality poster is printed on authentic blueprint paper, measuring 15.25 inches by 20 inches. This print is extremely high quality with all the details and notes very easy to read. It makes an excellent piece to have framed or to use as a reference when studying a Mark V helmet. We have inserted our company logo in a very small size on the bottom right of the print to ensure these are not mistaken for an original in the future.
