Brass thimble, 1.5 cm in diameter. Images show close-up of thimble following removal from the submarine and the thimble following mechanical cleaning and thorough 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.
Cast iron cover from the starboard deadlight with rubber seal on the inside, removed from hinge on interior of the hull plate. Images show x-ray photograph of deadlight cover, deconcreted cover with rubber seal in place, and cover with rubber seal removed after conservation treatment with subcritical fluid technology.
Assortment of non-military buttons made of mother-of-pearl, all following surface cleaning and desalination. Images show seven two-holed buttons in varying conditions, four four-holed buttons in varying conditions, forward face of one no-holed button with metal shank and brass hoop back, and the reverse side of one no-holed button with metal shank and brass hoop back.
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.
Silver suspenders/braces clasp belonging to Lieutenant George E. Dixon, discovered with the straps’ rubber elastic fragments attached. Images show the clasp following removal from the submarine interior with rubber fragments still attached, close-up of reverse side of clasp with concretion partially removed by mechanical cleaning, close-up of engraved initials reading "G.E.D." on front face of clasp following mechanical cleaning, and full view of front face of the clasp following mechanical cleaning.
Wooden object, possibly a bucket or small cask, made up of staves with a solid wooden end forming the bottom. Images show some staves and wooden end of bucket in its initial location within the submarine interior sediment, staves and wooden end of bucket laid out following initial cleaning, with some staves still concreted together, and staves of bucket reconstructed with velcro bindings following conservation treatment with polyethylene glycol and freeze drying treatment.
Hammer made of wood and wrought iron, found laying against adjustable pipe wrench in the bottom of the submarine interior. Images show the initial location of the hammer on the submarine interior hull, the hammer concretion together with the pipe wrench following removal from the submarine, x-ray photograph of the hammer following separation from wrench concretion, and the hammer following partial deconcretion.
Open ended wrought iron pipe wrench. Images show heavily concreted wrench in its initial location on top of ballast block, and wrench after cleaning, deconcretion and conservation treatment with subcritical fluid technology. Second image shows the extremely fragile condition of the wrench following conservation.
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.

Gold watch with attached chain and fob, found in mint condition. Images show watch in its initial location within the submarine interior during excavation, the watch with glass cover and sediment concretion on the glass, the inside watch face without the glass cover and the sediment contained within the watch, gears removed from the watch casing with evidence of corrosion, x-ray photograph of the gear mechanism, opposite side of the watch mechanism following conservation treatment, cleaned and treated watch with chain and fob, and close-up of the watch face and clamshell closure with glass and gold cover.
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). First image shows one face of the coin, which retains the face of lady liberty with the date 1860. The other two images show the opposite face of the coin, which exhibits the federal eagle and shield, as well as the words "United States of America" and "Twenty D." The coin has been intentionally filed flat for roughly half of its circumference and is inscribed with the following: "Shiloh...April6, 1862...My life Preserver...G.E.D."
