Hi Following up on Chris's clue, I found what is called a "Wundt style chronograph" at (see left-most image at top):
http://www3.niu.edu/acad/psych/Millis/wundtslab/gallery2.htm Perhaps this would be a reasonable approximation to Donders' device? I'll probably substitute it for the Hipp Chronoscope I currently use in lectures on this material. Unless someone finds something better?? Take care Jim James M.
