Trying to fix old cuckoo clock
As the title says. It’s an old Black Forest clock. The standard one with birds and maple leaves.
I ordered a new pendulum that was missing, but a small, round disc fell out of the back of the clock. It looks like a little weight…the same shape as a watch battery.
Before I try to take apart the clock housing, I’m wondering if anyone knows what this little disc is.
Thanks!
