Here it goes from Air Enthusiast 19 article 'The Vulcan...(Almost) A Valediction.'
I have a few pictures and 3-views of the Atlantic as I have a build project going for one of these. I have been in contact with a fellow who's name is Mike Meehan, he used to work in the Avro design office, and he sent me them, one of them shows the engines at mid span with the u/c between the engines and fuselage and has a distinct Comet forward fuselage look to it, where as the later drawings show something like a Boeing nose. Mike told me that had it gone into production (the RAF was very interested in it at the time as a tanker/transport) it would most probably have had the Vulcan B.1 wing which had the small kinked leading edge to it. There is also a very large model of this aircraft in the Avro Heritage Center, Woodford.
