SIEBE GORMAN & CO Deep Sea Diving Helmet 12-Bolt Antique 1880s

Antique, Circa 1880s SIEBE GORMAN & CO., SUBMARINE ENGINEERS, LONDON, PATENT, commercial deep-sea 12-bolt diving helmet, stamped serial # 3757.

Matching serial numbers except for one brail, excellent untouched condition for a working hat showing a lot of working dents. It went back to the factory for either some repairs or an update, the reason for a nameplate that was added on and covering the company Siebe name which originally was stamped into the breastplate in the early days. I removed the nameplate so other collectors can see this. I knew because of the serial number that the stamping was there under the nameplate. The rivets which held the nameplate are still with the hat, taped underneath the breastplate. Weighs approximately 36lbs. Measures approximately 17”H x 14”W x 16”Deep, front to back. Selling for collectible and decorative purposes, rather than use.

Before diving, equipment (this one) should be checked out by a certified industry professional.  Look at all the pictures and ask any questions you may have.
