I think that the photographs show the condition well - clearly it has had a life!  As you can see the whistle, handrails, and front coupling hook are present and correct.  The side valances are a little 'pushed in' from play use as is common on these - the brave could probably bend them straight again, with great care, but I doubt that the distortion is enough to foul the valve gear, and I don't think that it would show on a display model.
