One of the old Tesla company buildings is now the Brno Museum of Technology and the have (among many other) an exposition about the history of electron microcopy in Brno. One of the mashines that is part of the exposition (a huge experimental electron beam litography machine) is pretty much bolted in place in the same spot the old Tesla company built it all those years ago. There are even some "legends" about how they built it so well, that it is still holding vacuum inside today.
Another legend says that they once could not get a new model of electron microscope working before showing it on an international exposition. The image was always blurry. They ran out of time, so they just took it to the exposition to fix it there. But it worked flawlessly there! Turns out this was due to the tram troley lines running next to the company building interferring with the electron optics. :)
