Hmm, there are still many mysteries arround this system. The case is in sheet metal so it's very heavy but indestructible. It's impossible to open because all parts have been reveted. There is only one part removable on top with clips to place the 9V batteries.
The fact that the case is made of sheet metal means that only a few of these systems were produced. Indeed, plastic cases require a special and dedicated mould which is very expensive to make. Thus, the plastic solution was only adopted when large quantities of systems were produced.
All texts are in french. There is a little led that indicates whether the system is on or off. The two paddles are also in sheet metal. The problem is that we don't really know the brand of this system as there is only one name written on it - Sixplay.
