Help finding pendulum for antique marble French clock

[ap4840]

Hello, I'm having an impossible time finding the correct pendulum for this clock. It works great, just bed a pendulum to get it to slow down. Any ideas would be amazing! Thanks, Scott

Hi. Is there a makers mark/logo on the back plate.     I am at this time repairing two french clocks one by AD MOUGIN and SAMUEL MARTI,  both have pendulums of different lengths and weight. If yours has no marks it could be one of several makers such as HAC and others who produced clocks in the French style. Donald De Carles book “ Practical Clock Repairing has a chapter dedicated to pendulum lengths and weights and calculations to determine weight and length Clock Repairing. By Laurie Penman also has plenty of advise on the subject.  

There is what looks like a mark to the left of thr pendulum leader, could be an anchor, if so  GUSTAV BECKER

Certainly not GUSTAV BECKER. 4 8 The effective pendulum length is 4 pouces and 8 lignes; a pouce is an old French inch, and is 27.07 mm or 1.066", and a ligne is a twelfth of that, 2.256 mm or 0.88". So your pendulum should be approx. 126 mm long
