Recently, I had some code from a Subversion repository on my machine, but no longer had tortoise svn or any svn command lines tool set up. Luckily, I remembered that in Subversion there is a lot of fun data inside the .svn directory. For instance you can see the address of the server and repository by viewing the .svn/entries file at the root of the local subversion files.
Just look for the svn:// or svn+ssh://
That line should show you the svn server address, as well as the repo name and branch.
