... And now in a bold display of total ignorance, I can ask: Is a damper and a flue the same thing. I'm thinking the brass key thing was the original fireplace's mechanism to open and close the flue and still is.

I checked the yellow pages. It looks like they might still be in business.
The following links may help (two glossaries and two diagrams)

That part of a top-sealing damper that runs from the damper down the chimney to the firebox. It has a handle on the firebox end for the purpose of opening and closing the damper.
FLUE

Dampers
There are two locations for a damper. The Throat Damper is placed in the throat of the chimney, just above the firebox; the Top Sealing damper is placed on top of the chimney and operated by a mechanism that descends into the lower part of the chimney.
