Flight 93 Black Boxes; Authentic or not?

While researching the subject of Flight 93, it's hard to avoid Killtown's "Hoodwinked at Shanksville" and other works. http://killtown.blogspot.com/search/label/Shanksville

I like the bit in "Back in Black Boxes" that shows the 2 parts of the black box being labeled differently.

Apparently, Allied-Signal became AlliedSignal in 1993. It merged with Honeywell in December 1999. Flight 93 (N591UA) was delivered for use in 1996 (source)... also see this picture's details-- shot in 1996.

Example of AlliedSignal black box (FDR or CVR? see post below):

So notice the "H" for Honeywell on the cylindrical piece and the "a" in Signal on the other.

Is there a reasonable explanation for the labeling issue?

The FBI won't even discuss where the so-called black box and its twin, the flight data recorder, have been since their recovery Sept. 14 from the crash site, even though it is known that the voice recorder made stops at the Seattle laboratories of its manufacturer, Honeywell, and the NTSB's headquarters in Washington, D.C.

Asked to update the status of the cockpit voice recorder, Bill Carter, an FBI spokesman in Washington, D.C., said he could not.

"It's considered evidentiary," Carter said. "Therefore, it's not something that can be provided publicly to the news media unless there is a law enforcement purpose that can be served by release of such data."

What they measure

The cockpit voice recorder is a rectangular device encased in durable metal that is placed in the tail section of every commercial airplane. Microphones in the cockpit pick up voices and other noises, which are recorded on a loop of tape that starts anew every 30 minutes.

The flight data recorder keeps a running record of several aspects of a plane's flight, including altitude, airspeed and the craft's direction and pitch, all correlated with time measurements.

So, which is which? The flight data recorder is one. The cockpit voice recorder is the other. The sources for the images above (Moussaoui trial exhibit P200065 and P200066) shows the FDR as the cylindrical one and the CVR as the rectangular. But the NTSB shows - or seems to show - the rectangular one as the FDR:

Or not. See http://www.ntsb.gov/aviation/CVR_FDR.htm. It would seem the Moussaoui trial exhibits are indeed accurate. The image above isn't descriptive at all.

But, AlliedSignal is listed as the manufacturer of the FDR... and the label comes from Honeywell...
