Yeah, what you have said is pretty much what is known about the aircraft, and there is also a French Dassault MD-303 Flamant F-AZEN along side the Shacks.
All three aircraft were owned by Savvas Constantinides, Unfortunately he could not raise sufficient funds to set up his museum and with the three aircraft running up ground rent with the airport, the Cyprus Aviation Authority assumed the ownership of the planes and did nothing with them. Originally,they were parked up where the new airport terminal is now.
When the new airport terminal was constructed, and with the aid of personnel from RAF Akroitiri, the planes were moved to the west side of the airport, and parked just inside the perimeter fence.
WL747 was named " Florence " from The Magic Roundabout TV Show, and WL757 was named " Brian ", again from The Magic Roundabout. 8Sqn RAF Shacks were named after characters from the Herbs and The Magic Roundabout.
