Yorkshire Halifax comment

I can’t remember where I read it, heard it or saw it spray-painted on a wall, but I can recall a comment passed on the Yorkshire Air Museum Halifax recreation / replica:

“Although there are obvious departures from the aircraft depicted…….”

Now, I thought this was a bit harsh. Even taking into account my poor atrophied intellect, I can’t pick any ‘obvious’ departures from the design of a genuine Halifax.

Can someone enlighten me?
