Cocooning aircraft at Felixstowe 1950s

Does anybody have any evidence, a photo would be ideal, that shows flyingboats stored in plastic cocoons at Felixstowe during the 1950s?

It is known that some Short Solents were in store there after their time with BOAC, being eventually broken up when nobody wanted them. A report in the East Anglian Daily Times 17 Sept 1954 mentioned that they were stored in plastic “skins”. But I’ve also been reading other reports who say they were being worked on and coated with Lanolin to prevent corrosion. Does anybody have any evidence either way?

I would imagine the plastic cocoon is the same system used elsewehere, most notably with the Saro Princess. The aircraft were sprayed with two layers of plastic, one of a black bituminous material and then a final silver aluminium layer to reflect heat. Here’s a photo of some Lincoln bombers stored using the system:
