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.

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.
