SunTour 2 prong Freewheel removal woes!

I'm having a pain of a job trying to free a not-very-free freewheel.
Sadly, being new here I can't yet post the detailed photo I've taken of it.
Within the centre of the top cog, but outside the centre hole occupied by the axle, are two locking rings - the outer thinner ring has "MAEDA INDUSTRIES LTD" and "<<<------UNSCREW" stamped into it....it's 2 small grooves seem bevelled towards the outside.
The inner, thicker ring has "SunTour Japan VF (possibly VE)" and "Patent - NWN" stamped into it & the 2 slots for removal are 7mm long.
I've "made" a 2 prong tool from a socket but the whole thing just seems too tight (turning anti-clockwise).
I've also tried driving the smaller, outer slots round with hammer/punch, but again, no joy.
Does one lock the other?
Do both need freeing?
Is this one of those where I could simply turn off the top cog with a couple of chain whips?
I intend to keep/service the whole thing, so destruction is really a very last option.
Thanks for any advice given - I can't find an image or video on the internet for this particular assembly.
