Thanks, I used this in a WC:
svn log -v -r {2012-10-01}:HEAD URL
And it returned the few commits including affected files that were
involved from the start date. Not so many given that the project is so
old. But it clearly showed the bogus commits I want to recover from.

So now I know what has happened and I found the revision numbers for
two revisions that were committed erroneously last December when I was
preparing for the CVS -> SVN migration.
These revisions are 4309 and 4310

Now my problem is in finding the correct svn command to restore the
trunk files to the state they were in prior to commit r4309.

I have googled a lot tonight and read the svnbook too but I am none
the wiser (not so that I dare run a command and risk screwing up the
repository).
I have some candidates within the top dir of a WC of the
project/trunk:

svn merge -c 4308:HEAD .

svn merge -r 4308:HEAD .

svn merge -r 4309:HEAD .

svn merge -c COMMITTED:PREV .

Questions:
----------
1) Use -c or -r?

2) Which order of revision numbers?

3) What to do to restore to two revisions back?
