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.

Twenty-dollar federal gold coin belonging to Lieutenant George E. Dixon, its shape warped into a shallow "U" shape by a high-velocity projectile (bullet).
