Mechanical Clock Movements?

I bought a New Old Stock Mechanical clock movement made by Hermle 141-070K 43cm

I was wondering how or where can I find out information about it like the size of the bob and the weight used in the pendulum, the suspension spring and leader size, etc etc etc.

I know the pendilum length from the movement number which is 43cm.

I tried yaho and google searches but turn up nothing.
