Description

This vintage three-light, twelve-bolt diving helmet is a wonderful unrestored example, believed to have been manufactured in either Japan or Korea. Featuring the classic copper and brass construction, the helmet displays a rich, naturally aged patina that reflects decades of hard use and history.

The copper bonnet and breastplate thread together easily, although the original neck ring gasket is no longer present. The faceplate is missing one securing knob and currently cannot be unscrewed. One wing nut and one breastplate bolt are also missing. Internally, the original air vents and exhaust chin button remain intact. An interesting feature is the additional layer of copper reinforcing the top of the bonnet, a modification sometimes encountered on these hardworking commercial diving helmets.

With its distinctive appearance, authentic wear, and beautiful original patina, this helmet has tremendous character. An excellent opportunity to acquire a classic Asian commercial diving helmet that would make an impressive addition to any collection or nautical display!
