Many thanks for Hard Hat Diver Jacques Abdoun from France for sharing some photo’s of his ‘Équipe’. Jacques dives a 12 bolt 4 light Siebe Gorman helmet. This helmet retired in the late 1970’s after a construction job in the Harbor of Mutrah - Masqat, Sultanate of Oman. After Jacques obtained this helmet last year he restored it into working condition and took it back to the sea: he dives it with friends and family.
