So sorry ! ;D
But mentioning the Atlantique could be a good clue ! Maybe there is more,
than just a superficial similarity and the Aeritalia design was based on the
Atlantique fuselage ? The cross section is very similar, too.
Aeritalia was part of the SECBAT (Société Européenne pour la Construction du Breguet Atlantic) consortium,
so use of components for a successor doesn't seem impossible to me. The position of the tiny nosewheel
could be regarded as another evidence. Other opinions ?
