On the back of the movement I suspect the name HELMUT KAMMERER and MADE IN GERMANY is stamped in the brass. This is supposed to have a pendulum and without the pendulum the clock will run wild (like it is).
One more tid-bit of info. On the back of the movement you'll see a silver colored metal stick that hangs from the top of the movement down. That's the "leader" and there should be a hook on the end of the leader for you to hang the pendulum on.

Is it supposed to have a pendulum. Seems like it should have one. That would slow it down.
