I bought this C7 recently. The previous owner has removed all items from the case. The pendulum is missing. I have a photo supplied by the sellers father before dismantling the clock.
I am in the process of sourcing invar flat strip and 15 thou spring steel, these are theonly materials i dont have to hand for a new pendulum.
I will clean and reassembly the mechanism and send another photo. Also the pendulum compoents as the fabrication proceeds
