If a URL is 301 redirected to a new location on the same site, then later that redirect is removed and the content on the old URL restored, will the old URL regain (or come close to) its previous rankings?

Or, since it's a "permanent" redirect, is it likely that the URL will have difficulty ranking as well as it did previously?
