Working well and keeps good time. Had it running now for two weeks, has a nice soft ticking noise.

Simply turn the little pendulum screw very slightly either way to adjust time.

It seems (via Google) most of the clocks from this era were German, makes like Haller, Kienzle etc.

It is a chiming clock, which can be annoying to some (to me anyway), I move the coil away so I can't hear it
