3007) I'm going to make some possibly unjustified assumptions about this one. 1) That it is a stainless steel. 2) That the inner end of the holes is well smoothed.If so --it could be to hold cut film (4x5") upright and allow full access by developer through the holes (probably with something like nitrogen burst aeration) to be used for developing, stop-bath, fixing, and washing of the film in a light-tight tank, or in a dark room.
Is that wood at the bottom? If so, I hope that it is wax covered so it does not absorb and retain the chemicals for one of the baths to carry over to the next.
3008) A changeable bit hammer impact drill. The tapered part shown as a crossbar is the "drift key" to remove the tool, which is fitted in a tapered socket. Usually used with Morse tapers, but I suspect that this is a different taper because it is so short.Probably for drilling holes in concrete, and the rubber handle protects the hand holding it from most of the shock from the hammer. (And the mushroom upper end protects the hand from the hammer during misses. :-)
3009) If it had a bottom, I would think that it is intended to hold a candle as a form of lantern. (And I guess that one could clip in there.)Lacking that, a cage for a petrified snake stood on end? :-)
3010) One end is a straight screwdriver blade. The other is to drive a special head with a single offset hole into which the pin fits.The pin -- and the slug of which it is a part, appear to be spring loaded and slide into the sleeve of the body, to keep the wrench from simply rotating around the pin.
3011) Not enough detail and angle of view to really tell about this, sorry. Perhaps if I had seen one as part of the whole machine, I would recognize it.3012) The left three are intended to drive into two pieces of wood, and to draw them together.
The right-hand one appears to be for joining two pieces of wood at right angles to a third piece, forming a 'T' joint.
Now to post this and then see what others have suggested.
Enjoy, DoN.
