United States Navy Mark V Diving Helmet (Reproduction)

This item is a reproduction of a United States Navy Mark V Diving Helmet, characterized by its traditional heavy-duty construction. The primary materials are polished copper for the main 'bonnet' or headpiece and brass for various fittings, including the faceplate, grid, and securing elements. The copper exhibits a warm, reddish-brown hue with areas of natural oxidation and some smudges, indicating handling and a developing patina. The brass components show a golden luster with some darker tarnished spots, particularly in recessed areas, which adds to its aged aesthetic. The helmet features a prominent circular faceplate with a thick clear viewing port protected by a brass grid, secured by several small screws. Below the faceplate, a brass plaque is affixed, bearing the inscription 'UNITED STATES NAVY / DIVING HELMET / MARK V - MOD I / SNOW & DOUGLAS CO. LTD.' and 'MADE IN INDIA'. This clearly indicates it is a manufactured replica. The design also includes brass 'wings' or dog ears on either side of the front, used to secure the helmet to a diving dress. One such dog ear is visible on the left side of the image, showing its robust construction. The overall craftsmanship appears to be a good quality reproduction, with attention paid to the aesthetic details of the original Mark V helmet, though the 'MADE IN INDIA' stamp confirms its modern origin and manufacturing location rather than historical operational use. Visible condition issues include minor surface abrasions and the aforementioned smudges and developing patina, consistent with light display use rather than heavy wear. The word 'FRONT' is also clearly embossed on the lower brass ring, serving as an orientation marker. Despite being a reproduction, its substantial material and detailed construction evoke the iconic appearance of a genuine vintage diving helmet.
