This view of a standard Hurricane Mk IIA (P3351, brought back from Russia by the late Jim Pearce in the 1990s and now preserved in France) provides a direct comparison with Z3687 - note the continuous uncranked line of the wing leading edge, and its blunter nose radius.

Главным внешним отличием Convair 990 стали обтекатели на крыле, названные "Kuchemann carrots" ("морковки Кюхемана").
This superb plan-view photograph of a Convair 990 clearly shows the large and distinctive - and apparently unnecessary - "Kuchemann Carrots" anti-shock bodies on the wing trailing edges.
