If I were to post some of the earlier Italian rotary-wing designs I would have to go hide under a rock somewhere
Dare I mention... Fiat 7002?
It was one of a number of prototype helicopters I remember from 1960s editions of the Observers Book of Aircraft - the Piasecki Pathfinder and Filper Beta (which looked rather like the result of an illicit union between a Bond Bug and a CH-46!) are two others that have surfaced amidst my mind's flotsam.
That Bell 48/Agusta 102 does look a bit like an early and rather ill-defined Bell 204, any commonality?
