Proplinerman,
I visited East Fortune last year and unfortunately the situation with the Vickers Viscount remains the same, fuselage indoors, wings parked outside. I think the BAC 1-11 they have there, G-AVMO, is the ex Cosford aircraft.
The BOAC 707-436 forward fuselage section is in the Concorde hangar. However the fact that Concorde has a hangar all to itself is one of the reasons that the Viscount sits in pieces, theres very little room left to put it together in the remaining hangars where all the other exhibits are squeezed in.
