Half a Siebe Gorman standard 6 bolt helmet dating from 1920-1940.

Copper and brass throughout with side viewing window, comms and air, hanging posts and lashing eye.

Siebe Gorman makers badge underneath and a Siebe divers knife.

Knife sheath mounted on the board and knife can be pulled out. Stamped to the blade very faintly SIEBE GORMAN.

An unusual piece, we've had one before in 40 years.
