This is a very nice unrestored diving helmet, likely made in either Japan or Korea. This is a 3-light (windows) 12-bolt diving helmet in the classic configuration. The helmet is complete with a great patina on the copper body and brass hardware. The bonnet & breastplate are currently stuck together. The faceplate is missing both knobs. Internal air vents and exhaust chin button are intact. One of the vents is pulled away from the bonnet slightly. Take note of the helmet’s construction style and the seam on the back left of the bonnet. This helmet has a lot of character, making it the perfect display piece!


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.
