Friends with a '20s Tudor had a pull-button that connected to a lever that pushed a door button about 8-10 up the wall -- so it appeared to be a pull-button, but was actually a standard doorbell with a fancy push apparatus.

Many pull buttons are just low voltage electrical switches that activate any low voltage electric bell or chime anywhere in the house. Mine is from 1891.

Are you referring to something purely mechanical like mine, or something wired?

There's one for sale at the local salvage place for $150 with all of the components.

Here's the bell apparatus from the inside. The outside is a knob on the left side of the door frame (it's a Baldwin knob I reconfigured to re-use the original post, etc. inside but still be able to match the new door hardware, but it used to be either brass or bronze).

Kevin, you have the coolest place.

I'd love something like what you've got, Kevin, for our back door, but a regular chime for the front. I'm wondering if I can get a chime activated by a pull-button apparatus instead of a push-button. Maybe that will be awkward for people though. What I really want is something that doesn't seem contemporary. Our exterior hardware is from Rocky Mountain Hardware in a brass-ish color, but made of bronze. It's not the most Georgian thing, but it works with our multipoint system. Anyway, I don't know if I should just get one of theirs, maybe a simple circle or rectangle, or try to find something really cool and historic looking.
