Upon opening the box, you will find 3 grey sprues, plus one clear sprue, instructions and a medium size decal sheet stencils included, for two finishing options, one in overall high speed silver and a camouflaged one.
The part count is, relatively speaking, low with a total of 59 parts. The only real assembly option is the external tanks type, either conformal tanks from the Mosquito or drop tanks. You have to either choose which one to install or to fill in the holes in the lower wings.
Perhaps the “main” issue with this kit is that the Vampire Mk.9 had an asymmetrical wing root (to accommodate an internal AC unit), but the plastic parts have symmetrical wing roots, making the kit a Mk.5. Personally, I am not all that worried about that, but some modelers might want to take note of it, or get aftermarket decals for a Vampire Mk.5
