4 Cell ?Light Saber? Flash Questions (Sorry if this is out of place)

Hi just received an old 4 cell light saber style flash, but I have a

few questions? I guess the simplest question is do any one know if

there is a website with instructions for one of these? Barring an

Instruction manual I have some questions on the operation of the unit.

It seems a lot more complicated than the late 1960?s vintage model I

have for my crown Graphic. Firstly what dose the switch on the side

do? Is it an on off switch for the button that fires the gun and

solenoid? And why dose that button unscrew to reveal a bi-pole

connection?

I know what the household connection on the front is for connecting it

to the solenoid on the lens board. But what are the over bi-pole

connections around the flash for? Also there is a wire with a bi-pole

female connection on it (to connect to the lens) that is screwed into

the front of the gun.

And one final question I have never been able to work out. When I

connect a flash handle to the solenoid and fire it the flash fires as

well as the shutter but nothing is recorded on the film almost as

though the shutter is opening after the flash. So how dose one work it

so you can be firing the camera from the solenoid and use the flash.
