My wife inherited a brass anniversary clock in its original glass dome. It used to work but when we moved house we lost the suspension spring and fittings.
It looks like a Gustav Becker, but there is no maker's mark just a serial number 18929 below a 0.
It doesn't have a suspension spring guard or any screw holes to indicate it ever had one. The pendulum weight is a flat disc with two small weights adjusted by a threaded pin. There are no markings or serial numbers on the disc.
Unfortunately the threaded pin is broken at one end of the centre section that goes through the mount above the pendulum disc.
As for the suspension spring and fittings, does anyone know what size they should be? The drop is about 130 mm. To fit into the claw on the case, the top block must be 7 or 8mm wide with a 12 mm long pin. To fit the claw on the pendulum disc, the bottom block must be 2 to 3 mm wide with a 5 mm pin.
Does any of you know which model this is, and what reference numbers I should look for when try to find the missing parts?
