Morbier Clock. 'Marciac'. Chime lever.

One thing i did notice while stripping and cleaning was a little lever with a hole in it for a pull cord and a corresponding hole directly below it in the frame.
I have read that this is to enable the owner, in the dead of night, to check the time. Pull the lever and the last hour chimed is repeated. Fantastic. I have visions of a series of pulleys and a long cord from the clock leading to the bedchamber!
I suspect that a high proportion of these clocks though were never cased and just sat on a suitable bracket on tne wall so a simple toggle under the clock would suffice.
