Iron plate with attached view ports
1860, 1869
Exterior hull plate, hemispherical (semi-circular), made of wrought iron with glass view ports. View ports include hinged cast iron deadlight cover with wrought iron pin lock on the interior of the hull to prevent light from appearing outside the submarine during night drills. Images show plate and view ports following submarine excavation and hull plate removal, x-ray photograph of view ports prior to deconcretion, view ports following deconcretion (removal of sediment concretion), and full deconcretion of hull plate and view ports, including the removal of glass and hinged deadlight covers.
