Right, some help required if possible. 
With some old photography kit we have lying around (just filters and such) there is also a flash, as I don't actually have one I was thinking of playing around with it a bit so was wondering if anyone had used one and knew what the settings were.
It's a Hanimex TX475 (I'm guessing around 20 years old, and pretty cheap?)
At the front it has a little switch (Just below the "auto" and "off"), with the position shown showing an "M", sliding it across shows a green section with what looks like a bit of glass. Is this something to do with light metering? (which I assume won't work with a 400D?).
Next, the back; an on button, a ready light, and a force flash button, the dial I assume is the adjustment when the switch at the front is set to manual? I'm guessing you twist the outer bit round to the distance and then read off the aperture (yellow) to shoot at with the set ISO(ASA)?
Hopefully I can put it to some use with a homemade diffuser for some macro work.
