So it was eventually revised into 2 papers, and published elsewhere, in 1976. I decided to scan it to have it on my files, and in case anyone else was interested. It contains some accounts of homotopies and a Whitehead theorem, not published elsewhere, except as part of work in the mid 1980s with Philip Higgins. So this is now available, as they say "as is", on my preprint page, http://pages.bangor.ac.uk/~mas010/brownpr.html which also has a recent presentation on John Robinson, sculptor.
