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.
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.
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 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.
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.
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.
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.
Metal suspender button loop and portion of chain made of silver. Images show concreted loop following removal from submarine interior and initial cleaning, loop following partial deconcretion by mechanical cleaning, and mostly deconcreted loop following mechanical cleaning with chain portion still partially concreted.
Brass buckle with two prongs, possibly from a vest. Images show buckle following removal from the submarine interior with surrounding sediment and textile, and buckle following rinsing, cleaning, and thorough drying.
Clay smoking pipe bowl and stem, discovered in 2 pieces. Images show pipe in its original location within the submarine interior, stem and bowl pieces of the pipe following initial cleaning, and reconstructed pipe following conservation treatment.
