Thanks, Tim!
Yep, the Centuri SST had black and yellow decals also. Semroc replaced the Centuri in the rudder decal with "Semroc." It also says "Semroc 2005" on the outside fin circle decals, around the lightning bolt; I don't know what, if anything, was written on the Centuri original. There's a color shot in the 1972 catalog over at the Ninfinger Model Rockets site.
BTW, speaking of decals, this part of the SST Shuttle decals always got me. Here it is next to the OT's "vent" decals. Perhaps it was Centuri's way of acknowledging the debt to the OT???
