2. Wooden bench support
- Date:
- 1860 and 1869
- Description:
- 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.
3. Iron rudder
- Date:
- 1860 and 1869
- Description:
- 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.
4. Iron bolt and nut
- Date:
- 1860 and 1869
- Description:
- 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.
5. Iron tool handle
- Date:
- 1860 and 1869
- Description:
- 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.
6. Iron file
- Date:
- 1860 and 1869
- Description:
- 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.
7. Forward wooden shelf
- Date:
- 1860 and 1869
- Description:
- 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.
8. Wooden bench
- Date:
- 1860 and 1869
- Description:
- 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.
9. Cast iron cover of starboard deadlight
- Date:
- 1860 and 1869
- Description:
- 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.
10. Hammer
- Date:
- 1860 and 1869
- Description:
- 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.
