Norden bombsight
The Carl Zeiss Lotfernrohr" 7 ("Lot" meant "Vertical" and "Fernrohr" meant "Telescope"), or Lotfe" 7, was the primary series of bombsights used in most Luftwaffe level bombers, similar to the United States' Norden bombsight, but much simpler to operate and maintain. Several models were produced and eventually completely replaced the simpler "Lotfernrohr" 3 and BZG 2 bombsights. The "Lotfe" 7C, appearing in January 1941, was the first one to have gyroscopic stabilization.
