Nation's Attic Diving Into History Auction 2025 + More
Lot 54:
Description
One of the most desirable and rare American diving helmets is the 5-bolt pattern made by the A.J. Morse company in Boston, Massachusetts, also known as the US Navy Mark 1. This style of helmet was used by the US Navy in the late 19th Century and early 20th Century before the Mark V made its debut in 1916. Commercial divers would also use this style during these time periods.
This model is unique in that the bonnet (top) and breastplate (bottom) are secured together via 5 large bolts at the neck ring. Traditionally, helmets were threaded together, but some favored this style. While the US Navy used the 5-bolt pattern, helmets in their inventory after 1916 were generally retrofitted into a threaded style, making the surviving 5-bolt helmets quite rare.
Even rarer is to find a helmet in its original, unaltered condition, like this one. This example was made circa 1890-1900 based on its very low serial number of 891, located on both the bonnet and breastplate neck rings. The helmets brass ID plate is one used for a short period of time and rarely seen. This style of ID plate has the company information stamped into it, rather than cast. The plate reads A.J. Morse & Son; Boston, MASS; U.S.A.
This helmet was just recently discovered by a family in the northwestern part of the US. The family’s grandfather had used this helmet. A photo of the man will accompany this helmet.
As shown in the photos, this helmet is in its original, as-found condition. The unmistakable green and dark brown patina of a 120+ year old helmet is found on the copper body and brass hardware. All five of the bolt work. One of the ears on one bolt is broken off.
All of the original brass hardware on the bonnet is still present including the communications and air elbows, early non-return valve, communications cap, exhaust valve, window guards, glass, and communication cup. The faceplate threads on and off without issue. Miraculously, no notable or large dents are present on the top of the bonnet. The air fitting is pushed in slightly; otherwise, it is in excellent condition. All the internal air vents are intact.
The breastplate does retain all twelve of the bolts. It is missing the four brails and twelve corresponding wing nuts. An old leather cord is wrapped around the breastplate’s neck.
This helmet can easily be left as it is or have the missing parts fabricated for it. We seldom have a helmet with a family history tied to it, which we will pass along to the winning bidder. This big and imposing helmet will instantly impress just about anyone, even if they are not a collector!
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.
