An unusual French open escapement clock.
An unusual French open escapement clock
This one was not working when I purchased it at an auction for more that I should have paid (one of my early purchases). I started to dismantle the movement and discovered that, among other things, the striking hammer was broken. I did not have a replacement and could not find one from any clock supply sources. So, I took it to a local clock repair. I asked him to repair the striking hammer and he asked me if I needed the movement cleaned, I said no and left the store.
