This is a 2 weight German wall Vienna regulator. It is a time and strike clock on a gong at the hour and the half hour. It is apart at this time, but all the finials are here. The style is called the Serpentine, mostly due to the curve of the door.
This is the top of the clock showing the details along with the porcelain face.
This is the bottom of the clock showing the weights along with the finials, laying in the bottom of the case, and also shows the pendulum.
