The funnel is described as bright blue with a small letter.
These are recorded as alternatives. B431’s letter colour is unspecified and assumed to be white.
Alert at London on 12 May 2001 confirms B428’s royal-blue funnel. Rosanoski considers B432 probably the same funnel and therefore expects a similarly shaped italic letter on its flag. The small design derives from a monochrome photograph of Velox.
