A year ago I got a badly damaged and incomplete Brillie clock. The main lack was a pendulum. For many months, the original could not be obtained and the refurbished clock could not be started. I found a colleague who thoroughly photographed the pendulum and gave me detailed dimensions. The most difficult to make was a magnet that was made of a steel bar. Carburizing, hardening and magnetization gave full success. The rest of the elements are just precision machining. I had to make a new set of contacts and a wooden case. The clock after adjustment works without a problem on a 1.5V battery.
