|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?

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...
