Yes, Steve's right.
Here's a pic with my edits showing the single landing light and the 3 AoA lights on the nosegear door. It also shows the blisters (only one visible in the pic) where the Shoehorn ECM AN/APR-30 S/C/X-band Radar Homing & Warning antenna were mounted. The Shoehorn Mod was a spec from the USAF's RF-4Cs, which the USMC planes then inherited when they ordered additional C airframes to complement their original order of B model RFs.
BTW - and yes, I know JP will want to reach in through his monitor and choke me for asking ...
but is there any chance this RF-4B, if added/released, could have extendable nose gear?

Finally, where did you guys get the last two USMC paints? I should have been all over those and confess I never knew they existed ...
