Question
I have acquired a Haller movement Westminster/Whittington chiming clock. I understand that the clock works, but there seems to be a part missing from the pendulum. I have found a small piece of what looks to be very thin spring steel in he case. This could at one time have been joined on to a small pivot pin which I also found in the case. The rest of the pendulum is there but I am unable to hang it anywhere. Could you please advise me what I should do to get the clock working again.     
  The movement is stamped Haller/foreign No.276558 14cm/178

Answer
The pendulum assembly begins at the top with a 1" two legged suspension spring pinned to a brass post sticking out of the back of the rear movement plate.
  Next a silver(probably) suspension leader about 5" long that hooks onto the bottom of the suspension spring and passes through the "foot" shaped forked brass piece (and must be in the center of the fork slot and not be rubbing front or back) that connects into the inside of the movement.
  Lastly the top of the pendulum hooks onto the bottom of this suspension leader. NOW if all is correctly assembled, swinging the pendulum will get it ticking. The sound of the ticking must sound even or balanced on either side. Not over-swinging one side or the other.
  If it is not sounding even, then push with your hand the top third of the pendulum over to the side that has the excessive overswing. You may feel some resistance but gently push a bit more then try the sound of the ticking after swinging the pendulum freely.
  If the sound is not improved in the balance then do more pushing -if it is now sounding like excessive swing in the opposite direction then push the pendulum to the other side till it sounds a pretty even tick. Clock should run then.
    Your suspension spring is broken and needs to be replaced. There are many different sizes and shapes. Not sure of what a Haller like yours would take.
