The caption posted reads ' ... nose radar and bomb sight obliterated by a censor'.
I'm guessing this is from a caption printed with the photo in a book, and was just pointing out, for the benefit of those who may not know, that bomber Mosquitos were not fitted with 'nose radar'.
No slight against you intended, but many books now publish incorrect, or downright wrong, information which, in the fullness of time, could, and in many cases will, alter the facts of history for future generations. It might seem a minor and pedantic point, but the more this happens, the more the problem is exacerbated, to the point that such important, literally World-changing events as WW2 could be viewed as a minor conflict by future generations.
