Sources differ between a panel and band on the alternative funnels. Photographs and plans support a band in the earlier E1 comparison, while Sincerity shows a panel occupying the side’s full width without extending around. Mitchell gives bands for both. Asperity in March 1983 has a yellow-cream funnel with the narrowest black top; Brown 1978 also gives E2 a narrow black top.
Only this alternative funnel is documented; the flag is assumed.
