I am working on Revell's kit. It is the Heller's one: you are right, Revell includes the decals for instruments...quite nice actually. My first impression about this kit is that it needs some extra scratchbuild, but oob assembly can have reasonable results as you show us. The plastic does not receive the pigment very easy and sometimes the green plastic come out. I preferred to fix the pigments with clear varnishes to avoid any accident.
