Description

This exceptional commercial diver’s helmet was produced by arguably the most famous American helmet maker of the time, the A.J. Morse & Son Company in Boston, Massachusetts. A prime example of early 20th-century design, it features the characteristic elements of that era. Stamped with serial number 1845 on the bonnet, breastplate neck rings, and all four brails, this helmet’s manufacture can be accurately dated to circa 1914. Remarkably, after 111 years, it remains a complete and original serial number-matching set.

The helmet retains its four serial numbered brails, twelve wing nuts, four copper brail shims, communications cup stamped Craftsweld, communications fitting, exhaust, air fitting, AJ Morse non-return valve, spring loaded safety pin, glass, port guards, neck ring gasket, original brass ID plate, three removable eyelets, exhaust chin button, very old reproducer (speaker) and a single copper internal air vent.

This helmet tells a story of practical use and adaptation, a common characteristic of vintage diving gear. Like many helmets used by commercial divers that saw extensive service, it underwent modifications based on a diver’s preferences. The presence of a Craftsweld communications cup and fitting on the back indicates the addition of a communication system (uncommon when the helmet was originally made). Furthermore, the original internal air vents were replaced by a single copper pipe vent, aimed to provide direct airflow across the front faceplate. In a somewhat unusual design decision, this added pipe now partially obscures the top port window.

This helmet bears the undeniable marks of a long and industrious career, undoubtedly serving on countless underwater tasks across decades. Its beautiful copper body proudly displays the typical scars of hard work – numerous dents and small, expertly executed hole repairs. Subtle modifications to its brass components further whisper tales of its working life. Today, this veteran of the depths shows minor signs of its age, including a cracked glass on the diver’s left side port, two missing faceplate studs, and a missing gasket. To preserve its earned patina, a clear lacquer was applied after its active service concluded.

“If you have been looking for a classic American diving helmet made during the early 20th Century, this one would make a great choice. This complete #s matching helmet features a great patina while being a clean example suitable for display anywhere.”
