ROLLER DISCO Pinball machine from GOTTLIEB (1980) in Gameplay

Greetings from germany. My memories go back to 1981. I haven't come across this pinball machine anywhere since then. All in all, it is a rather rare model from Gottlieb's System 1 series—a "widebody" that, despite its massive dimensions and insane weight (HELP!!!), offers a fantastic gaming experience. It joined my collection by sheer coincidence. I am absolutely thrilled!
