I recognize parts of the old test from operational use a long time ago, but I don’t think it has been licensed to anyone else. It isn’t part of the big TPO collection ETS sells to Chinese schools.
Be wary if you download the bonus content. Some of it is out of date stuff that ETS doesn’t use on the real TOEFL anymore. I think it is content that was cut from the test so that it matched the revisions in 2019. You won’t get an open-ended speaking question, nor a campus problem speaking question. You probably won’t get a “fill in a table” reading question.
