I have *no* idea why this was done, but it is kind of amusing.
Update! [05/05/00]

Douglas Snow informed me that:
"When Engine fire handles are installed on the overhead panel, it's normally because JT8D-17A engines were installed."

Here is another view where you can see both the cardboard fire handles taped to the glareshield
and the real ones in the overhead.

Here you can see a very important indicator that's right above the ADI.  This is an Instrument Comparator.  It electrically
compares the values of the primary flight instruments on the Captain's & First Officer's instrument panels.  They are: Power Monitor, Heading, Pitch, Roll, Glideslope, Localizer and Alititude. In the three panels (separated vertically) you can see:

Panel 1:
Pull Up light
Airspeed Indicator

Panel 2:
Instrument Comparator
ADI (Attitude & Direction Indicator)
The upper right hand corner of the HSI (Horizontal Situation Display)

Panel 3:
Auto Pilot Disengage lamp.  This will illuminate if the AP disconnect button on the left ram's horn (left arm of the yoke) is pressed or the autopilot is otherwise forced to disengage.   MDA - Minimum Descent Altitude indicator (I *think*)
APD - Approach Progress Display.  These two rows of lights will illuminate to show the pilot the status of the current
approach.  Examples include "GS" for Glideslope, "VOR/LOC" for VHF Omidirectional Range/Localizer, etc.
Upper left hand corner of the Altimeter, Right half of the "Radio" or radar altimeter.  This measures the height above the ground by using a small radar system that sends pulses from an antenna located under the aircraft.  This is used when a more precise altitude report is needed when below 2500 feet than the standard barometric altimeter can provide. Right above the radar altimeter is an "Altitude Alert" light that will illuminate if the aircraft descends below a preset altitude.  You can see the altituded "bug" that marks the point where the Altitude Alert lamp will come on.  In this image, it's a little orange inverted triangle that is currently pointing to the 0 position on the instrument.  The little knob on the lower right hand corner of the instrument has an orange triangle on it and this is used to adjust the bug.  There is also a lamp in the upper left corner of the instrument that illuminates at the same time the alert indicator does.[?]
Last, there is a red handle marked "Pnumatic Brake" that is used (I think) to increase or decrease the pressure applied in the braking system - this may be related to the parking brake, but I'm not sure.  If someone would enlighten me with more detail about the function of this handle, I'll update this page and give credit.

Thanks to Scott Evans for pointing out the Power Monitor indicator on the far left of the Instrument Comparator.
