Just noticed the Green Sunderland in the last photo, This is a postwar Dr Grope reissue of a wartime 1/200 ID using the original tooling.
Also Corgi [Mettoy/Playcraft] made similar style models in the early 1960s under the Vapour Trails mark that are sometimes confused with Wikings.
These too had a wire stand, transfer decal sheet, ID style aircraft information sheet. The base of the stand, however, was a soft suction cup affair and if kept in contact with the model, it would melt into it.
There were 5 aircraft in the series, all British. The one missing from the photos the Sea Vixen
