Lap timer for Mini 4WD, with speed display function. Purchased over 25 years ago and kept in storage. The main unit has no noticeable scratches, but the box has deteriorated. I inserted batteries and the power turned on, but it's unclear if it actually works. Please consider this before purchasing. Instruction manual and 4 AA batteries are included. (Batteries will be removed from the main unit). - Brand: TAMIYA - Model Name: Mini 4WD LAP TIMER - Function: Lap timer - Speed Display: Km/h - Power Source: AA batteries (sold separately) Thank you for viewing. #Mini4WD #LapTimer
