I got hold of a (cheap) Italeri 1/48 Skyraider, as well as of a pair of Airfix Ju-52 floats, and their size did fit
(the profiled struts are optional wings end from a (very cheap) 1/24 Harrier for I have ongoing activity ...) :
the color can be thought of as a firefighting floatplane exercise, a role for which some Skuraiders were equipped I think,
and the floatplane relevance was convincingly established by e.g. movies like Planes 2.
