Paper, Spirit and Time - Exploring my collections

Vintage clock and timepiece collection

Here are some photo's from my collection of all kind of clocks:

A master clock is a precision clock that provides timing signals to synchronise slave clocks as part of a clock network.
Networks of electric clocks connected by wires to a precision master pendulum clock began to be used in institutions like factories, offices, and schools

A slave clock is a clock that depends on another clock, the master clock

An KWH / electricity meter or energy meter is a device that measures the amount of electric energy consumed by a residence, business, or an electrically powered device.Electricity meters are typically calibrated in billing units, the most common one being the kilowatt hour [kWh].
Periodic readings of electric meters establishes billing cycles and energy used during a cycle.

A time switch is an electrical control device that automatically turns electrical circuits on and off at predetermined times

A time recorder or clock, sometimes known as a clock card machine, punch clock, or time recorder, is a device that records start and end times for hourly employees at a place of business.
In mechanical time clocks, this was accomplished by inserting a heavy paper card into a slot on the time clock. When the time card hit a contact at the rear of the slot, the machine would print day and time information (a timestamp) on the card.

For all of the clocks I'm looking for the manuals and / or user instructions
