Spanner drilled tamper proof

and a Phillips screwdriver bit. In brick. At the Escher Wyss Platz in Zürich.

This area was once home to the Escher Wyss manufacturing company. They made many things, including two of the paddle steamships, Stadt Zürich (1909-) and Stadt Rapperswil (1914-) that are still in service on Lake Zürich.

One of these days I'm going to manage a great shot of all five bits. All I have now are mediocre-to-crap shots.
