The log is the place to look. I know you don't want to hear that answer, but that is where you need to look for deleted files in SVN.
The reason for this is simply that a deleted file is not visible after it's been deleted. The only place to find out about its existence at all is either in the logs, or by fetching out an earlier revision prior to it being deleted.
The easiest way I know of to deal with this problem is to move away from the the command line, and use a GUI tool such as TortoiseSVN.
TortoiseSVN links itself into the standard Windows file Explorer, so it's very easy to use. In the context of answering this question, you would still use it to look at the logs, but it becomes a much quicker excersise:
Browser to the SVN folder you want to examine. Then right-click on the folder icon and select TortoiseSVN -> View Logs from the context menu.
You'll now get a window showing all the revisions made in that folder. In particular, it is easy to see which revisions have had additions and deletions, because the list includes a set of Action icons for each revision. You can double-click on a revision to get a list of files that were changed (or straight into a diff view if only one file was changed)
So you can easily see which revisions have had deletions, and you can quickly click them to find out which files were involved. It really is that easy.
I know you're asking about the command-line, but for administrative tasks like this, a GUI browser really does make sense. It makes it much quicker to see what's happening compared with trying to read through pages of cryptic text (no matter how well versed you are at reading that text).
