1] General view of the WT movement including pendulum bob.
The large, drive electromagnets are missing in the open space at bottom right.
As is the ratchet, gathering wheel on its arbor with the vitally important drive worm.
The upper pendulum rod with its support bearings are present.
The masking pawl is absent. As are the Hipp toggle and V-block which control the contacts.
Two pale patches can be seen on the pendulum rod where once a cranked plate was fixed to support the Hipp toggle.
I believe the loose piece arranged in the middle is the relay magnet armature.
The relay electromagnet restarts the drive to the clock hands at each half minute by releasing the locking lever and masking pawl. This would allow an accurate master clock to maintain the WT to a similarly high, timekeeping standard.
The complete contact mechanism is also absent.
The L-shaped locking lever is also missing.
This would be lifted into the locking position by the D-shaped pin on the ratchet wheel.
The bearing plate to support the end of the ratchet wheel and worm arbor is present.
A small plate should rise up from the casting to provide a bearing for the relay electromagnet.
