I've owned this since new. It is the US version of the game as that's where it was purchased. Generally it's in great condition. All parts are there, including the spare bulb although this looks spent. One white piece ( can't remember what they're for) has snapped but both pieces present so can be repaired (see pics).

Electronics not working correctly. I cleaned the battery contacts which were slightly rusted ( see pics ) and it lights up, displays "0", then a flashing " -  - ". Pressing any of the buttons blanks the display and the unit makes a brief noise.
