"A person may have reasonable grounds to suspect that property is one thing (A) when in fact it is something different (B). But that is not so when the question is what a person knows. A person cannot know that something is A when in fact it is B. The proposition that a person knows that something is A is based on the premise that it is true that it is A. The fact that the property is A provides the starting point. Then there is the question whether the person knows that the property is A."

'...do not have an innocent purpose that readily springs to mind'

Being that its not a current V5 its not valid.

Whilst it is more than possible that a document like this could be used for fraudulent or other nefarious purpose, it doesn't HAVE to be!

Or looking at it another way, somebody has put a set of sprint mechanicals in another shell, and want make the car a "proper" sprint.
Doing that is, in law, no different to re-shelling a sprint with a secondhand shell. The identity is attached to the shell. If the old sprint shell is scrapped, so should the V5.... But we all know in the real world what does happen.

Of course, there is a very slim chance a sprint may be stolen and appear with this registration, but a bit obvious. Saying that, criminals are not usually very bright.
