Three J. P. Diem elevators from 1899-1900 in Berlin Charlottenburg, Germany

This video shows three similar Stigler elevators with three different stages of modernisation. I have been here with user WindHund27, expand description to find a link to his channel. These three elevators are located within upper class residential buildings in Berlin, Germany. One of them has the original birdcage cab, the second one a wooden cab of which I think it has been added on later. And the third elevator has been replaced by a modern elevator in 2014. But the old shaft doors and shaft framework is still there. Check out WindHund27's channel here:    / @windhund27
