1534 is the compressor in a jet engine or gas turbine
1535 looks very like a transmission stand for supporting the transmission or
engine when you're working under a car on a ramp. However it isn't tall
enough for a car on a ramp at head height so you can stand under it. Same
type of principle though.
1532 Radio Communications Receiver. Separate front end tuners for various
bands. Band select switch. BFO switch for listening to CW code
1534 Part of a cut-away turbine rotor.
1536 Guess... electrical firing trigger for a gun (cannon). Imagine that it
might be used in the turret of a WW-II Japanese warship. Thumb safety, pull
trigger to make bang.
That's a better guess than mine...I was thinking of a black-powder
starter's pistol, with the thumb mechanism as a backup for false
starts. But the construcion and style sure says 'military' to me....
Now I'm looking at either some sort of igniter to start old prop
planes (I don't know why I have this fixation that it uses powder...)
or else a trigger to set off explosives. The thumb trigger is the
BTW, a Mandarin-fluent friend of mine just told me what the writing on
the front of the item says:
"The first character $B0B(B is likely the phonetic rendering of some kind
of firearm (?) made by a company that starts with the sound "An"--
Anderson? The second character $B<0(B means "style" or "kind".
Not a lot of help....its a firearm-kind-of-thing.
Thanks! I was hoping someone would be able to translate that for us. I
agree with those who think it's some type of warship trigger. The owner of
it found it on a shelf in the cellar of an old adobe in Colorado.
Below are links to a few photos of an usual object someone found in
California, not sure if it really has a purpose or not , but I am a little
curious as to what it might be:
The owner's description:
"It is 6" long exactly, with the small end being 3/4" in diameter and the
large end being 1" in diameter. It is hollow all the way with the small hole
being 5/16" in diameter and the large hole being 5/8" in diameter. With the
insert installed the large end is 1-1/4" from the large end of the insert.
The insert is 1-1/2" long."
I agree that this is most likely the answer, but it has proven to be a
difficult one to verify. The rest of the answers, except for number 1533,
have been posted here:
I think you got 1532 wrong. It's not for listening
in on friendly bugs, it's for detecting hostile
bugs. It's a modular receiver that can scan the
entire spectrum from 1 mhz to 1600 mhz. A friendly
bug receiver would only tune to either the band or
specific frequency of the bug.
Shows the receiver in the lower right side of the
briefcase with a whip antenna connected to the
12-43 Mhz input.
I really don't know enough about it to agree or disagree with your comment.
I took the photo at a military museum, here is the uncropped shot which
shows the museum's description:
I'm sure it's possible that it's not marked correctly, or maybe it was used
for both purposes and they offer just a partial explanation of it. Thanks
for the link, they had some good stuff there.
The museum is description is likely accurate, but incomplete.
Such a receiver certainly could be used to monitor a bug. There are much
less expensive single band (or even single frequency) (and portable)
receivers used for that purpose, however.
We used to call this type of receiver "DC to Daylight".
Looking at that particular bug -- single frequency receivers
would have a problem. Note that the open-air coil (inductor) is
squished from its original shape. This would not keep it from working,
but it *would* shift the frequency. And it is so easy to
unintentionally squish it a bit more just handling to to its point of
operation. After all -- you don't walk past the front desk of the
embassy (or whatever) with it in the open resting in your palm. It goes
into a pocket until you are where you need to install it.
I also don't see a source of power in the photo -- though coin
cells might be hidden on the underside or otherwise behind other
components. I know that pressure transducer style microphones can be
small enough to be included in the components on the board.
I was impressed enough by the R-390A (if I remember it
correctly), which went from audio up to 40 MHz. Amazing mechanicals
inside, and tons of tubes. I remember being part of a communications
experiment which had us on an Air Force base in Arizona with three of
these operating in a duce-and-a-half -- generating a lot of unneeded
heat in mid-summer. :-)

Well, I don't feel quite as clueless as sometimes, but that's not saying
1531 - Quite obviously a little electronic circuit of some sort. It
appears to me to likely be a radio circuit, perhaps a cheap transistor
radio receiver, but it's impossible--at least for me--to tell without
being able to deduce a schematic for it. It may also be an amplifier or
timer or a host of other things.
1532 - Some sort of portable RF equipment, possibly an RF frequency
signal generator for testing other equipment. There are rather clearly
eight RF generator circuits covering a wide range of frequencies, but
it's not clear what the part in the upper-left is intended to do; it may
permit modulation of the RF.
1533 - Well, you hold the handle and....ummm....
1534 - Obviously some manner of a turbine; it doesn't look especially
sturdy to me, so I'll guess it's a large turbine air compressor.
1535 - I was initially going to say a piano stool minus the seat, but
it's too tall for that. Probably it's for an adjustable table of some
sort, maybe intended for a typewriter or such like.
1536 - Maybe a part of a paint spraying outfit? Seems quite complicated
for that, though.
Now to read other guesses...
"He is no fool who gives what he cannot keep to gain that which he cannot
1531 I am going to guess at a receiver judging by the coil and the variable
1532 amateur radio receiver
1534 some kind of turbine?
1535 I am tempted to say it a chair mechanism but i doubt its that simple.
1531) A small printed circuit board featuring two transistors (at least), a
small trimmer capacitor and a low inductance coil as well as assorted caps
and resistors. This could be anything working at a VHF frequency. I do not
see a crystal, so likely a front end amplifier of some sort.
1532) A wide-range signal generator with output regulation and modulation
1533) A toothbrush for very bad gingivitis
1534) A turbine. GOK for what purpose.
1535) A Jack - there is a coarse and fine (screw) height adjustment. OTOH a
table top may be missing...
1536) A firing mechanism of some sort. I interpret the kanji as Japanese
meaning "cheap model"
