Old Mechanical Calculator INCREDIBLE Restoration! Jewelry work!

In this video, I am restoring an old mechanical calculator. One section was jammed many years ago, and the former owner did not know what to do with it, and sold it to me at a very low price!

The breakage was not difficult, but it was difficult to get to it. After all, it is full of small screws and springs!

Did I manage ...? Watch this video.
