The original 'How to find snails at Brixton Market' page was hosted on my old Demon web server (which is why it never got preserved with the old Geocities stuff), which has long since gone. I did, however, have a back-up on an old zip disk (remember those?!). I have now pdf'd, then jpeg'd, the pages, and am displaying them here in case anyone is still interested! I went back the market in September 2012 (as you may already have seen) and nothing seems to have changed, so these instructions are still valid!
