Twelve-Bolt Diving Helmet
Manufactured continuously by Siebe-Gorman from 1837 to
1975, its name comes from the number of bolts which
project from the shoulder piece. The rubber and canvas
diving suit would be tightly clamped in place on these bolts,
making a watertight seal. The top of the helmet could then be
screwed in place. Used all over the world, the "Twelve Bolt"
was copied by many other Manufacturers, versions of it are
still produced in some countries today.
