If it's so important, why not employ some of those tools?
As always, Rob gave the answers.

3217) Looks like a tool for pulling difficult to extract nails.
3218) A wire stripper -- for heavy gauge wires. Looks like it bolts
down to a workbench, and it has small ratchet wrench as the
operating lever -- with a knob added to the handle.
3219) It looks more like an operating lever which clamps onto a shaft
(likely on a machine tool) instead of a tool in its own right.
3220) It looks to me to be an adaptor for something like a theodolite
or transit to a tripod. Likely one which is rather more
portable than most, based on how it folds up -- and on the
relatively small size. (Unless that is a scaled-up quarter of
The three points receive three hollow cone adjustment points for
setting the instrument properly level.
3221) Looks like something designed to grip the end of a leather
strap. (the center bar would prevent it from being used to
scrape a strap along its length, which otherwise might be be an
3222) Another interesting device.
My first guess (now rejected) was that it was for winding coils
with a known number of turns.
Instead, it is something for applying a twist to something held
between the two points, while one point is rotated a number of
The dial tells both how many turns, and how far the vertical
point has moved. The main beam is calibrated in 1/2" steps, and
it looks like the dial represents 0.001" per division (not sure,
with the 50-0-50 calibration, and difficult to get the gear
ratio without a view which lets me count the teeth on each gear.
At a guess -- the screw in the bar is 20 TPI which would allow
the 0-50 part to represent one turn of the screw and the crank.
Maybe it is for turning a really small drill bit, while feeding
the workpiece into it, but it is difficult to see both how
various sizes of drill bits could be held in the rotating part,
and how various workpieces could be held in the vertical part.
Now to post and then see what others have suggested.
3222 used to twist wire. The slide on the bar controls where the
twisting starts to occur, and the holder on the top does the twisting.
The counter keeps track of the number of twists put in. Nice little unit.
pretty good the last few weeks...
Machine tool lever sounds like a good guess, but no luck yet finding a reference
Well, I have a few answers posted for this set, still waiting on the others:
I have a tool like that but with a metal handle. It is used to hold an
inside bore gauge to reach deep into a bored hole.
I think not. This one has a projecting point which tightens
with the handle, and which goes into a dimple in the micrometer body
(probably on the side away from us in the photo).
The one in the puzzle is clamped from the sides, with a stronger
grip (not needed nor desired for a bore micrometer), and the heavy wood
handle suggests a significant amount of operating force needed.
I still think that it is an operating lever for some machine
The vertical holder has a projection into a groove on the bar,
where it engages a leadscrew on the same shaft as the handwheel. So, as
you crank the handwheel, the vertical holder is moved either towards or
away from the "headstock".
But what I *really* wonder about is whether the horizontal
holder rotates with the geared screw in the top, or whether it remains
stationary. Knowing that could help determine what it really does. If
it does not rotate, then a wire strain gauge is likely. If it does,
then either a self feeding drill assembly is a possibility -- or it
could be a tool for straightening wire (twisting wire under tension
tends to straighten it).
There is nothing to indicate that the holder on the bar is screw driven.
As a matter of fact quite the opposite. There is a knurled lock nu that
indicates it's really stationary. So I don't believe it travels the
rod... if it did why would it lock?
I don't know the purpose of the knurled lock nut on the vertical part but I
there and watched someone turn the handle and the vertical part moved along the
rail. I still haven't heard back from the owner about whether the other part
rotates, though I don't think it did.
There actually is -- both the groove on the upper back side of
the bar leading in to the leadscrew which is inside the bar, and Rob
H.'s posted observation elsewhere in this thread.
Why not? Lock it while during setup and while zeroing the
dial's pointer, so you start from a known place.
Just as all of my lathes, whose carriage is intended to move
along the ways, have a lock screw and wrench to use when facing instead
