2263) To keep either water or foodstuffs warm. 2264) Throwing (toma)hawks? 2265) This looks to me like the worm part of a steering worm and sector gear. 2266) Perhaps a semi-portable water distillation setup?
Looks as though the level is to make sure that the condensate runs to toe collector not back to the boiler.
2267) Either for picking up a hot vessel by the neck, or for picking up ice. Probably the latter. Maybe even for *dry* ice. 2268) This one is quite clear to me -- though the line is rather short for normal use.It is a "ship's log" -- used for measuring speed through the water. The part on the left is trailed behind the ship, and the dial, hooked to the transom or someplace similar, indicates how many turns the towed finned object turns in a given period of time. It can give either speed (distance over a measured time) or overall distance travelled, if the dials can accumulate enough turn counts. Looks like not a high enough count for a total distance travelled application, so go for the distance over a measured time.
Now to post and see what others have suggested. Enjoy, DoN.
