Classic alarm system WACH-O-MAAT in new old stock condition. The vintage alarm system comes with a nice small switch, mounting parts, instructions and with box. It works with 6V and 12V and it is about 11x11 cm. The alarm system was made in Germany about 1960. The function is very simple. Inside is a pendulum and as soon as the car strongly wobbles the alarm system will switch on the horns. So you can just hit the bumpers a bit and the horn will go on and off and you are a show winner. An accessory for classic VW Beetle, Bus, Type 3, Karmann Ghia and Porsche.
