Ring my bell

Off to pick my car up from the garage.
Oil change, new tyre.
The start of a new week.
Football tonight.
Another victory please.
Here is an old bell push.
Now idea how old
It is one of a pair on an old building.
This is the left sided one, there is one on the right side of the door also.
Unusual to say the least.
The don't work though, and it's opposite number doesn't actually have its button in the middle.
