OK then. I have me a wrench, and a suitable socket, which i managed to fit into something resembling a drain plug. I have tugged and tugged and tugged until finally the decade-old seal of gentle corrosion broke, and fairly quickly eked it out after that. About a teaspoon of slightly gunky looking fluid came out, and that was it.
Now i'd like to know if anyone can be so kind......
* did i get the right plug (only opening the filler so far, to check the level)
* should any more have come out (consider that the car is jacked up just high enough at the front to allow me and my nose clearance from the sump on a low-profile creeper -- but nothing at the back -- ie it looks like it could double for one of Sir Hilary's sherpas
* does this look / sound dirty enough to need renewal
* how in the hell am i going to refill it if so, particularly with any accuracy or cleanliness (i think draining it "cleanly" will be hard enough)???

spent a merry hour farting around underneath the car, only to realise that (unlike before, with shorter handled tools) I could probably do it far easier from above. Maybe should have jacked it down first though...
(still wasn't easy - could maybe do a click at a time, bending the expansion tank slightly out of the way in one direction, then stretching the pipe in the other.. luckily after a while it became loose enough to finger-spin it out)
i've put it back in, loosely, for now. car's not going anywhere after all.
