Wilhelm Conrad Röntgen - Working X-Ray Machine

W.C. Roentgen was a German physicist who discovered the X-rays on November 8, 1895 at the University of Würzburg. His groundbreaking discovery made him the first scientist to be awarded the Nobel Prize in Physics. His findings revolutionized the field of medical diagnostics and led to other important discoveries of the 20th century, e.g. the research of radioactivity.

This 249 piece model shows W.C. Roentgen during his research work in his laboratory. A simple lever mechanism activates a light stone that casts the silhouette of a skeleton onto the inside of the window. Since I was only missing a few pieces I was able to build a prototype which you can see here:
