I bought a wall clock at a yard sale. I looked on the back of the case and written on this case was Gustav Becker Freiburg /Schl. So I assumed this was a Gustav Becker clock. To my surprise it had a Junghan 104 1/2 movement. I am trying to find out the approximate time when this clock was made and why it has a Gustav Becker case with a Junghan 104 1/2 movement. Attached are pictures of this clock after my restoration.
