it looks very much like a Vulcan; is that the first guess you were anticipating?
That is indeed the first guess I was expecting, and it is incorrect.
I'm going to call foul on the Vulcan guess and say that Deltic is being sneaky as I think it is in fact a Vickers Valiant.

Ainsworth however cottoned on to my trickery and got the correct answer.
My rouse of course was that the Avro Vulcan and the Vickers Valiant have very similar cockpits, the Valiant however has slightly larger direct vision windows.
Here is the full image, which if I'm not mistaken shows a Valiant K2. (though i stand to be corrected if i am mistaken.)
