Thanks for responding and sorry for the slow response - I was away for a few days.
I've managed to pick up a Cap copy m- for £90.
Its really difficult at the moment to try and establish where prices are, hence my caution.
Thanks for the info - I've seen the one on discogs but its VG+.
From a previous discussion on soul source I think it looks like the Part 111 may have ben the local release and the Cap City, probably released at a similar time had a wider distribution.
It amazing just how much information people have about relatively obscure tracks.
