A public clock of the style on the left, double sided and in any condition, even if not an impulse clock.

A short pendulum Smiths or English Clock Systems master clock similar to the "Memory Master" clock shown on the right.

Low battery Warning Bell shown on the left, of any make, eg Synchronome/Gents

Impulse driven calendar similar to that shown on the right.

Interested in any programme machines of the type shown on the left, used for ringing bells etc.

But I am particularly interested in finding an IBM/ITR Telephone Rentals type of programmer similar to that shown on the right.

Any waiting train tower clock movement of any size. Two types are shown here.

If you have anything interesting relating to slave clocks or slave clock equipment I might be interested. In general I am not desperately seeking any master clocks other than the ECS model above, I prefer to collect the slave equipment.
