A very large German FMS Mantel Clock.
This one is a little unusual in that one can see the pendulum through the beveled glass window in the front of the clock.
Time and strike movement is of reasonable quality. I like the large sound of these strike-only clocks. Good rule of thumb: the larger the case, the better they sound. This one has a very high quality gong.
I completely stripped the movement on this one to clean and rebuild it. The springs were excessively dirty because someone had packed the spring barrels with grease which had hardened over the years.
