(I'm not sure if this is the correct forum for my question, but if not I will be told, I guess)
Recently I discovered a funny thing about Phantom FGR.2's 'middle canopy': some have this part of the canopy as a window, but others have it in solid metal with a periscope or something like that poking through.

XV480, July 1985:
Can anyone tell me the background of these different versions?
Cheers,
Rob
