I can't find a scan of them either !
The only unique decal for this kit is the "Athena" logo that is on the payload section.
This decal has a very unique font and is fairly small in scale. I suppose one could use the kit name (same font) on the instruction sheet and reduce it about 30% and print it on decal paper.
I can use a "Nike Smoke" decal for the "United States" on the booster; it is the same.
Opposite (180 degrees around the circumference) the "United States" on the booster tube is an "Enerjet" logo which is easy.
I can use the wrap stripes from a red "Aero-Dart" decal set.

Phred: Could you combine all of these in one decal set ???
If so, how much $$$$ ?

Anyone have a full-scale fin pattern ?
I could "guesstimate" it but I'd rather not.
