Z313, Z317 Frames: Rear Exit Blacked Out-No Limo Stop-Tape Incongruent w/Med Evidence-Z 6K Enhanced

Dino Bugioni & Doug Horne with Wilkerson-Whitehead 6k Zapruder film enhanced from 3G National Archives copy (the same one, as I understand, as Groden's).
Opening Bugioni scene was only released recently, on Kevin Hofeling's channel from the raw footage of Z Film Mystery.
