Bosch stopped making relays fifteen years ago. They sold the business to Tyco. If you find a Bosch labeled relay today, it's very old NOS. However, the terminal identifiers on almost all relays today are DIN standard, so relays of any brand can easily interchange.

The relay you picture is weird, in that it has two 87 terminals. It's more usual to find either a single 87 contact or an 87 and 87a terminal. The latter is called a switchover relay: 87 is normally open, 87a is normally closed. When the relay is powered, that reverses.
