Longcase Double-Ended Suspension

Longcase or Grandfather clock suspension used at the top of the pendulum which flexes allowing the pendulum to swing freely.  Fitted with a brass end at the top, which is riveted through the steel strip to retain it in the back cock. The opposite end is fitted with the bottom block. This is slotted  across the top to allow the suspension strip to locate inside, which is then held in place by a pin, which fixes both parts together. The bottom of this block is drilled and threaded to receive one end of the pendulum rod.
