The suspension bracket and pendulum bracket are also nickel-plated, the movement plates are not. It is a newer clock (the owner remembers buying it in Germany around 1972 or 1973) and has a very thin base that warps easily. It is 7 1/4 inches tall without the dome.

I polished the pivots and replaced the suspension spring. It uses a .0023 inch thick suspension spring, unit 12F (but about 1/8 inch longer). Horolovar back plate no. 1406G.
