Butz,
The black and white you posted is the first #1 that didn't have the gun port or the full vertical fin root fairing. There aren't too many pictures of this aircraft because it crashed on its second flight.
The first two color pictures are the prototype F-14A+ with the GE F110 engine. Its first flight was in 1981.
The last picture is BuNo 157991, Aircraft 1X, late in its career, with extendible canards (the black panels) on the forward fuselage near the nose for spin recovery assistance. Note the windshield in front of the RIO's position that was on this particular aircraft.
