3205 I'll guess that these are [ancient] Chinese multiple rocket
launchers. They hold 100 rockets, with arrows as stabilizing sticks
that are fired as a barrage. I'll guess further that these are
reasonably modern museum exhibits.
3205, colonial baby carriage for India
Fakur babies in training.
3206, either radio directional antenna,
fly swatter for huge flies, or egg wisk.
3207, radish cultivator, for small gardens.
3208, embossing tool for rail road tickets.
3209, no clue.
3210, no clue.

3205) A strange thing. Is it perhaps a portable device for crushing
3206) An egg whipper?
3207) Some sort of fork designed to easily slip off whatever it picks
up by operating the lever.
3208) O.K. Another interesting device. First off, it is built on a
parallel-acting jaws pliers. The size looks close to that of
the metal-backed buttons/pins, but the left-hand part is too
small to assemble one without bending the backing plate, and the
pliers are not really offering enough leverage to make it
practical for this use.
So -- I don't know.
3209) The tapered square to the left looks like what is found on the
shafts for winding tall clocks -- but it is the wrong gender to
fit into a clock.
Out of curiosity -- which direction does the ratio go? Is the
left or the right hand side the faster?
And how heavy (wide) are the gears? If they are thin stamped
steel, they don't have the torque to drive much significant
Perhaps it is for something like spinning a wheel with holes in
it to act as an "optical chopper" -- or maybe a hand-powered
3210) Strange -- and I can't see enough of it to be sure, but it
looks like it could scribe a diametrical line across the end of
a piece of round stock. (More detailed photo of the spring
loaded arm might give more clues.)
A tough series.
Now to post and then see what others have suggested.
O.K. About medium strength, then. And while I don't know which
side is up,. the side on the top is the high speed, and the one on the
bottom is the low speed. (Assuming that the center gears shown are
directly connected to the shafts. No real depth to the photo -- even if
I save it and adjust the gamma to make it less dark.
Maybe it is supposed to have a fan blade on the high speed end,
and be used as a hand-cranked breeze in hot weather?
Or -- as someone else suggested -- for a hand cranked grinding
wheel (a quite small one). If it had a way to clamp it on a table edge,
it could be for sharpening scissors or something similar. But I seem to
remember a wooden handle under the gear housing, which is awkward for
most grinding uses.
Given that additional clue, before going to see that one -- let
me state a secondary guess. It is for deforming plastic watch and dial
indicator crystals. Push the center in relative to the ring and the OD
shrinks a bit. Drop the bezel ring onto it so the edge of the crystal
fits into the groove there, and relax the grip on the pliers to let the
crystal expand into the ring.
I made something to do this -- using a drill press and the press
part instead of pliers.
Now to see what the "hidden" answers really say.
Yes! I wish that I had seen this before I needed to make a tool
to do this. (I used mine on crystals for various sizes of dial
indicators of the sorts used by machinists.
I hope that this one has interchangeable parts, to adapt it to
larger or smaller crystals. I had to make (so far) three different
