That red '69 RR looks like it was sprayed pretty much downward, looking at the flanged openings; the cars I've gone by appeared to be shot upward, with black on the bottom yoke and the underside of the flange, but none on the top of the flange. Maybe more variation than I was aware of?
My dark blue '63 had no blackout, but my '64 did. Can't recall my old dark blue '68, but my dark green '69 had blackout, as did my red '68, and the lighter-color (white, lighter greens, & turquoise '68s - '70s I've owned.
