I really hope the owner of 2144 is not in Texas:
http://www.txdps.state.tx.us/RegulatoryServices/narcotics/narcprecursor.htm
"In 1989, the statute was amended and requires anyone who sells,
transfers, furnishes, or purchases certain precursor chemicals or
certain laboratory apparatus to be regulated by DPS. "

""Chemical laboratory apparatus" means any item of equipment designed,
made, or adapted to manufacture a controlled substance or a controlled
substance analogue, including:"
...(D) a three-neck or distilling flask
(H) an Erlenmeyer, two-neck, or single-neck flask
(I) a round-bottom, Florence, thermometer, or filtering flask
(here's my favorite...)
(K) a transformer

2143: corkscrew variant?

2144: volumetric gas mixing chamber. Used with other plumbing to hold
low-pressure gasses to make accurate gas mixtures, like the Ne-He mix
to fill a neon lamp.

2145: the terminals are four-way binding posts, it's probably a
battery
box for a toy kit with motor or lamp bits.

2146: Gerbil cage? I was thinking crab trap, but the inner parts
aren't
suitable, and for a bird cage, it looks amazingly undamaged.

2147: Rugged case and clip, electric power and what looks like
tube fittings... with an electric meter movement. Dunno; maybe
some safety-check equipment for aircraft support crews?

2144: It reminds me of a receiver jar. They are used on dairy farms
that use a piplene to milk cows. The milk goes from the milker and
then into the pipeline. Then into the jar and gets pumped out of the
bottom and into the bulk holding tank. The extra hole is for a probe
that senses the level of the milk and turns the pump on and off to
pump out the milk.

I realize that some citizens of the US, have misinterpreted the name
Australia and confused it with Austria, which are approximately 9000 miles
apart
But, although Austria is close to Germany, let us not confuse the subject
further
Wilhelm was a German and had nothing to do with flight recorders at all.

Wilhelm Cauer (June 24, 1900 - April 22, 1945) was a German mathematician
and scientist. He is most noted for his work on the analysis and synthesis
of electrical filters and his work marked the beginning of the field of
network synthesis.

Don't know where you got your information from, but, this may clear things
up for you:

Dr David Warren of the Aeronautical Research Laboratories in Melbourne,
Australia invented the "Black Box" flight data recorder. He was the first
person to conceive of the idea of recording the flight crew's conversation
on an airplane and of protecting that recording in the event of a crash or
fire. The purpose of the Black Box was to help identify the reasons for a
plane crash, by recording any clues in the flight crew's conversation. The
Black Box was invented in 1953 and in production by 1957. The first ones
were painted bright red or orange to make them easier to find after a crash.
In 1960, Australia became the first country to make flight recorders
mandatory in aircraft.

Amazing. This might be the first time something did not turn out to be

I have no confusion on any of these topics. Geo Frost indicated that the
term black box was related to flight recorders.

I point out that Wilhelm Cauer was the originator of network synthesis
for the transfer functions of black boxes in the 1940's.

I haven't been able to find another one like it on the web, I would guess
it's laboratory related as few others have also suggested, although a couple
of people think it might be milking related. Still a mystery for me right
now.

I also think it's a battery but haven't found any proof.

Your second guess is closer.

Once again your second guess is better, and maybe partially correct though
not specific enough.

Could it have been to press carpet into a corner? To press oakum or

That's it! The tool is an ice block carrier, when you bore into it the

A fucking "TRANSFORMER?" Like a cell phone charger? A naked MOT[1]? How is

I believe the first time the world saw a famous black box was December
26, 1908. It was in Sydney, but Burns was Canadian and Johnson was
American.

In response to Jack London's appeal, Jeffries offered to prove that the
white man was king of them all in 1910. Friends dragged him from the
ring before the referee could count a knockout. Whites rioted in 50
cities across the US. In a joint project, film companies made a
$250,000 documentary. Congress banned transporting the film across
state lines. Teddy Roosevelt, until that point an avid boxing fan, said
the sport should be banned.

Johnson was sentenced to federal prison because he'd once had a white
girlfriend. He went on a world tour instead. Then he invented a new
wrench. He returned to the US and took up residency in Leavenworth so
he could get in patented: 1,413,121. I don't know why Rob hasn't
displayed it!

You seem to have confused "famous 'black box'" with "'famous Black' box."

One's a noun, the other's a verb.

Despite the color scheme, this is called a "black-box test".

Posting from Rec.crafts.metalworking as always.

2143) Tool for deburing the other side of a drilled or punched hole.
Drilled is more likely to have limited access to the far side.

2144) If the Pyrex logo is a round green color fired onto the glass,
then it is some form of chem lab equipment. There is a lot
which has been special modified for an unusual task.

This may have started as a sphere with a single neck, and the
other two were added by a glassblower at the lab in question.
Given the angles of the necks, I suspect that it was for
reacting at least two gasses, and drawing off the results in yet
another direction.

If it is such a modified piece of labware, it is unlikely to
have a specific name.

It does look to have plain necks, not the ground glass fitted
ones for coupling directly to other glassware -- so whatever it
reacted probably would not attack rubber stoppers.

2145) Lots of possibilities -- most of which would be supported by the
presence of markings on the box somewhere.

It looks as though the two binding posts are not on the
standard 3/4" center to center spacing, so I suspect that it was
someone's home-made product. (The reason for the standard
spacing is so standard dual banana plugs can fit into it, not
needing a separate connection to each post. The posts will
accept banana plugs, wires (through a transverse hole under the
knobs) and fork terminals.

The fact that two different colors of binding post are used
suggests that it is polarized - but it may also simply represent
what was available from the piece of equipment which was
canibalized to supply the binding posts. These are the cheap
ones which were used on Heathkit equipment, and likely from
Radio Shack stores as well.

I don't see the normal insulating mounting spacers, so the box
itself is likely plastic, not metal -- unless it is a dummy
device not really intended to be connected to.

What is there could be:

1) A standard cell (1.0194V or so) -- but there should be
a marker to not turn it upside down. (Standard cells
really have to sit on a shelf forever undisturbed.)

2) A standard resistor (no need for polarity there), but
there should be a marking showing the value.

3) A standard capacitor. If electrolytic, the polarity
markings from the colors of the binding posts is useful,
of course. Again -- no markings to show the value
inside.

4) A battery (polarity makes sense there, of course), but
again, no markings. And -- no obvious way to replace it,
though the bottom could be open. We don't see that
view, so we don't know.

5) Intended to look like an explosive device.

6) Something which I have not yet thought of.

2146) Some kind of trap or remote-release cage. I note that the
floorboard appears to be under stress, which might be used to
shoot the door open or closed.

2147) Looks like something designed for rolling a groove between a
curbstone and the grass alongside it -- or alongside a sidewalk
or driveway.

2148) Looks like something designed to measure some characteristic
of a gas -- and to adjust the flow of it. It looks as though the
meter dial is marked in percent, and it appears to be an
electrical meter of some sort.

There is a hose barb on the right. The left might be an
adjustment knob or some form of calibrating plugin.

There is an old mil-standard connector on the other end of the
cable.

I don't know whether the hanging loop pivot does anything else
as well -- since it appears to be knurled for either adjustment
or field removal and replacement.

Now to send this off and see what others have suggested.

Enjoy,
DoN.

Well Joe, the famous "Black Box" which was invented by an Australian and is
in every aeroplane, is orange.

Ive never seen such a tool,
however theres a possibility that its to do with brewing, specifically
for the removal of the oak? filling bungs? in wooden beer barrels.
these filling bungs are hammered in flush with the barrel so its not
possible to get a purchase on the bung to remove it without getting to
its underside.
