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.
Metal file composed of wrought iron, initially found resting on top of a ballast block on the interior floor of the submarine. Images show the initial site of the iron file during excavation and the file after deconcretion and conservation treatment with subcritical fluid technology.
Wooden shelf from forward bulkhead in the submarine interior, found laying horizontal to the original upright orientation of the submarine. Possibly made of pine, approximately 1 inch thick, with cut-outs to fit in the bulkhead of the submarine. Images show wooden shelf within the submarine interior during excavation and wooden shelf after removal, conservation treatment with polyethylene glycol, and freeze drying. Note the rust stains on both ends where bolts had been used to secure the shelf.
Half of wood pencil separated along the center where lead is contained. Images show pencil during screening of material in sediment bucket and pencil following cleaning 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.
Iron tool handle cast in a T-shape, with a square end. Images show the tool following removal from the submarine but prior to deconcretion, x-ray photograph of the tool, and the tool following deconcretion and conservation treatment with subcritical fluid technology.
Wooden tool handle, possibly for an awl or file, egg shaped on one end to fit the hand and tapered down on the other. Images show the original location of the handle within the submarine interior with the tapered end lodged between a ballast block and the aft bulkhead, the handle after cleaning and conservation treatment with polyethylene glycol, and handle after freeze drying.
Metal identification tag/medallion with notation for its owner Ezra Chamberlain. Images show each side of the tag following cleaning and treatment, the first reading "Ezra Chamberlain, Co. K, Reg C. T., Volunteers, Enterd Service, Sept. 6 1861", and reverse side displaying a profile of George Washington.
Rudder composed of wrought iron, discovered on the exterior of the submarine beneath the stern end with a large portion portside. Images show excavated rudder with concretion of coral growth and sea urchin spicules, rudder following partial deconcretion, deconcreted rudder treated in caustic solution, and fully deconcreted and cleaned rudder.
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.
