The scope is for electronics, and is probably WWII surplus -- I had
3. They generally work well when warmed up, but don't bet on getting
parts!
HOWEVER, don't throw things away! Contact a local antiquarian! I
donated/sold much of my very old equipment to local amateur radio
people, and got a fair chunk of money from the antiquarians for the
other stuff so that I could then go out and purchase some new stuff.

I am the same way. This is my first year and I have inherited so
much stuff that I don't know what it is. The school informed me to
put together a list of the items and they will determine whether
they are junk or not. The cords on most of the stuff is so old that
it cracks if you try to move it. I know we have a scope from one of
the World Wars (which I don't know what it has to do with Physics)
and several other things.
If need be I might eventually put pictures up to see if anybody can
help me determine what some things are.

Hello,
I have some familiarity with inheriting old equipment -- mine was
20 -30 years old (or older, I have since discovered) in the 80's
when I arrived. The easiest way to ID stuff is to see a picture.
Since you've got a website, maybe you could put up a few pictures
of things as you go along and we could all try to help you? I also
know a few antiquarians who specialize in scientific equipment that
I can refer to the images if you do that and they also may be able
to help.

Hello, all!
I'm in my second year of teaching physics. When I started, I
inherited a ton of equipment (much of which is still packed in 20-30
year old newspapers from when it was shipped to the school) and am
trying to figure it out as I go along. This one has stumped me,
though. If anyone knows what this is and how to used it, I'd sure
appreciate some help.
The device seems to be an optics demo of some sort. Initially, I
figured it was the one where a, upside-down lightbulb inside the box
makes an image on top of the box, but now I don't think that's
correct.
It's a little larger than a shoe box, made from wood, has a plug and
switch that turn on a 150 Watt floodlight mounted on the short,
handled side of the box. There is a compartment that pulls out to
reveal the light inside. There is also a series of overhead
projector-style lenses and mirrors, some of which have adjustable
positions and angles.
I'm not sure if they go together, but I found this with a small
piece
of wood that has 1 lightbulb socket on the top face and 2 sockets on
the bottom face.
I'm also interested in making one of those lightbulb image demos.
Is
there anyone whose made one recently who could offer suggestions on
how to build, where to get the mirror, etc.?
Thank you very much!
