The basic illustration follows Stewart. Brown makes the circle and associated device span the funnel’s full width and brings the flag emblem almost to its edges and point. A sighting of Matupi at Timaru on 21 October 1978 describes an “A” with a horizontal bar across its top and outward horizontal feet, confirmed by Nüsse’s table flag; the sighting did not record a swallowtail. Mitchell shows the “A” touching the sides of the ring.
