what is this? Old equipment

[sunray18]

I found some equipment in a dim dark cupboard and am wondering if anyone recognises it.
What is it? How is it used? It has a label that say "Frey Scientific" so I have emailed them to see if someone there has any idea...
Ok – without being able to draw on this computer … it consists of a plastic ruler attached to a metal plate, with a clamp-type attachment on the metal plate.
Imagine a ruler being held parallel to the desk..
On the back of the ruler is attached a metal plate 125mm x 75mm .. the plate is attached so the 125mm is along the ruler…
Then on the back of the metal plate is a clamp screw with a bar that looks like you can clamp it onto a retort stand or similar…

So when you look at the front

Yes Sunray, what is it?????

I know that there is someone out there whose imagination will take off on seeing that stupendous drawing and "name that piece of equipment".
We could start a new game show.
How about it Sunray? You can do the drawings and WE CAN GO CRAZY!

I think you are right Maree a new game guess what this is ?

I think it is some sort of experement for bad students and they have to put it together and then watch it untill it moves and then pull it apart :::::::::::::::::::::::

Its Physics equipment for light experiments, and for using the laser etc. You can set the little bizzos at specific intervals and shine lights in a straight line etc etc. They are still sold at Scientrific etc.

I still think it should be a experement for bad kids
