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.
Pencil composed of wood and coal, split into two halves. Images show the pencil pieces following its removal from the submarine interior sediment and pencil pieces following cleaning and freeze drying treatment.
Cylindrical canteen stopper made of cork. Images show two conditions of the cork stopper, the first showing the cork stopper following removal from submarine interior and initial cleaning, and the second showing the cork following super critical treatment.

D-ring shackle made of iron, used to support the spar boom as part of the spar torpedo system, uncovered from suction pile excavation area about 2.3 m forward and to starboard of bow. Images show shackle following excavation with thick and compact shell and sediment concretion, x-ray photograph of shackle, and shackle following deconcretion, conservation treatment with caustic solution, and cleaning.
Leather wallet belonging to one of the crew, made of two sides that fold in, once stitched together, and an additional pocket inside, with a reinforced band of leather for closing. Images show the wallet during the excavation of the submarine interior and the wallet following cleaning, conservation treatment, and freeze drying.
Large plank of wood, possibly pine, with an associated detached smaller plank, found in the submarine bow interior. Possibly cut from the same wood as the crew bench, the two pieces were nailed together at some point to construct and hold in place against an iron pipe the main seat for Lieutenant George E. Dixon. Images show wood bench in its initial location within the submarine interior, wood bench with detached support prior to deconcretion and cleaning, and deconcreted and reconstructed wood pieces following conservation treatment with polyethylene glycol.
