I don't know if this has been discussed before, but if you look at the picture I have included in this post, you can see that there are some frames to the left of the artificial horizon... why are they there if there is no gauge there?

The top cutout looks about the exact same shape and size as the backup artificial horizon in the middle of the panel. As previously mentioned though, it's not at all uncommon to see that on airplanes. Almost every Cessna built, for example, has unused cutouts.

727EMflyer, you brought it up a generation or so, but actually now a days that indicator you are referring to is called a PFD. The primary flight display has lots of info on it, not only all the stuff a flight director has but speed & alt & trends and on & on. The other big indicator to the right of it is called the ND for navigation display

The upper one (square with angled corners) is an alternative location for the clock which is actually located below the Standby Horizon and Standby ASI on this aircraft, and the lower, larger, circular one is the Captain's speaker. I suspect that if you had a shot of the F/Os side The speaker would be there but the provision for the clock would be missing.
