Wooden four-holed Army buttons with depressed center, made possibly from ash or similar wood. Images show buttons in varying conditions pre-conservation, four buttons showing forward face following cleaning and freeze drying treatment, and two buttons following cleaning and freeze drying treatment, one showing forward face and one showing reverse side.
Brass Confederate artillery buttons with stylized "A" on forward face and inscription and thread loop on reverse side. Images show the forward and reverse face of the buttons, with buttons in varying conditions following removal from submarine interior, four buttons after cleaning and conservation treatment with forward face showing, and two buttons, one showing forward face and one showing reverse side with eyelet and inscription reading "Halfmann & Taylor, Montgomery", after cleaning and conservation treatment.
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.
Silk bandanna or neckerchief belonging to crewmember James Wicks. Images show the bandana following removal from the submarine interior and the bandana following cleaning, soaking, conservation treatment, and freeze drying.
Wooden plank used as a bench for crew operating the crankshaft, with notches carved out to fit around the frame ring supports. Images show the third section of the bench alongside the second bench section within the submarine prior to removal and the 3 different sections of the bench after cleaning, conservation treatment with polyethylene glycol, and freeze drying. Note also the carving in the front of one of the sections, which was done by a crew member to better operate the aft ballast pump.
Wooden part of bench for supporting and holding forward and central sections of the submarine interior bench, with notch cut out to fit around the submarine interior frame. Images show the concreted bench support following excavation and removal from the submarine; reverse-side view of concreted bench support; x-ray photograph of bench support; bench support following deconcretion, conservation treatment with polyethylene glycol, and cleaning; the reverse-side view of the same post-deconcretion condition; bench support following freeze-drying; and the reverse-side view of the support post-freeze-drying. Note the holes in all images where nails or screws were once held to attach the support to the forward and central bench.
Binoculars composed of copper alloy barrels (painted black), a horn focus knob, iron pins and 6 elliptical lenses as opposed to round. Images show the binoculars following removal from the submarine interior and initial cleaning, and binoculars after extensive soaking, cleaning, and conservation treatment.
Large bolt found on top of the head of a hammer and an adjustable wrench in the bottom of the submarine interior. Images show an x-ray photograph of the bolt prior to deconcretion, the bolt with concretion, and the bolt following deconcretion and conservation treatment with subcritical fluid technology.
Nut and bolt once connected to iron bar in between interior aft pump and horizontal rod support. Images show initial connection to iron bar in the submarine interior, x-ray photograph of the bolt and nut and the adjacent bolt, corrosion of the bolt and nut after removal from concretion, and bolt and nut after conservation treatment with subcritical fluid technology.
Plain non-military buttons made of bone with depressed center and primarily four holes, though some contain five holes. Images show a small sample of twelve buttons of varying conditions before initial cleaning and desalination, seven buttons of varying conditions following cleaning and desalination, and thirty-five buttons of varying conditions following initial cleaning and desalination.
