There is an un-documented feature of the activity log script, without a user interface to access it - the f= paramter, when supplied with the LDraw path to a part shows all the Parts Tracker history for that part.
e.g. http://www.ldraw.org/cgi-bin/tracker/act...s/x882.dat
However, this does not currently show where a part has been renamed too, only where it came from, which is not very helpful in answering the current question.

Let me see how easy it would be to fix.
