Foothill Model Works' SP steam loco decals, now available from San Juan Decals http://www.sanjuancarco.com/sanjuandecals/sp-decal-sets.html . Note the unused Champ decal set for the F-5 class 2-10-2 that came with Balboa model. The FMW decal set comes with very comprehensive instructions and notes for application of the decals to all classes of SP non-Daylight painted steam locos from 0-6-0 to 4-8-8-2 Cab-Forwards. You'll notice this is the set I used (see cut out decals) to letter my F-5.
