Here is a rare opportunity to own a very desirable 19th-century American diving helmet. 
 
This helmet was made by the Alfred Hale Company in Boston, MA, during the 1800's. The helmet features a fantastic patina and is a seldom-seen neck feed model. The air elbow fitting was located on the back of the breastplate with the air channel located within the neck, blowing the air out below the diver's chin. This rather curious configuration was preferred by some divers, with only a precious few surviving today. 
 
In addition to the helmet's incredible patina, the castellation seams are clearly visible on the top of the bonnet and the shoulders of the breastplate.  This helmet pre-dates the common use of a separate ID plate. Alfred Hale Co Boston is clearly stamped into the front lower edge of the breastplate. 
 
The air fitting does have a old air control valve which appears to have been welded on. The air fitting has some vintage repairs around the base. Typical working dents are present on the top of the bonnet and in spots on the breastplate, all of which only add to this helmet's visual appeal and authenticity in our opinion. 
 
The non-recessed neck ring does have a very old gasket. The faceplate also has a gasket. Likely from decades of use, the faceplate is a bit loose initially when threaded onto the bonnet. All of the glass is intact as well as the window guards. 12 wing nuts and 4 brails are present. 
 
Without a doubt, this helmet has been on many jobs, likely over 100 years ago. Its incredible condition combined with the unmistakable patina will make this helmet an impressive showpiece anywhere it is displayed.
