This nice, early commercial diving helmet bears two plaques: the maker's plaque- "A.J. Morse & Son, Inc., Boston, Mass." and beneath it the distributor's plaque, "Supplied by Mussens Limited Agents, Montreal, Canada".
The helmet is in excellent condition with a nice patina, very clean and complete.
The helmet bears matching serial numbers 1846 on the front and rear brails, and on the bonnet and breastplate. The front and rear brails are also stamped with additional maker's marks, "A.J. Morse & Son, Boston". Interestingly there are additional hand tooled marks on the brail the diver must have added for his own reference: RF, LF, RR and LR for right front, left front, right rear and left rear.
