204B
FAA registration gives this as 204B, S/N 1501, built 1963, but registered Feb 5th, 1970 to Bell in Ft Worth; cancelled Dec 4th, 1980. Reason - 'Destroyed'. So I don't think that sheds much light on the situation.
Perhaps a collaboration with Agusta? Didn't they have a version (not very satisfactory) with a Gnome engine for Europe?
