a simple doorbell

After 2 and half years, we finally have a working doorbell.

We when first got the house, there was a non-working electric doorbell in the hallway and a non-working mechanical bell on the door. We’ve finally gotten around to replacing the mechanical bell. There is a twisty piece outside and a bell dome inside. Turning the twisty spins 2 chains with clappers and it sounds like this.
