Does anyone know how to get the proper sized weight for a Vienna wall clock that doesn't have weights with it

There are different sized weights for different Vienna movements. What movement do you have?

 

[Dick Feldman]

The size of the weight (diameter) can be measured from the clearance in the case as well as the distance between the weight drive cords.
The weight of the drive weight can be determined by setting the movement on a stand and hanging a scale (similar to what fishermen use with two hooks) on the drive cord/pulley. Secure the bottom of the scale to the floor and wind the clock. Run the clock movement on the energy stored in the scale. When the clock stops, what is shown on the scale is the minimum amount of weight that will be required to run the movement. Add 25-30 percent to that value to assure reliable operation.
We would still like to see pictures of the clock and especially the rear plate of the movement.
Best Regards,
