The blue flag has a red diamond containing a white J over a white R as a combined emblem. Brown 1951 shows a smaller diamond than the other sources. Two funnels are described: one blue with a very broad red top and a broad flag band; the other red with a black top above a broad flag band. In each, the diamond touches the band’s upper and lower edges.
The blue funnel band may have a narrow edging against the red: Stewart and Brown 1982 show black, while Brown 1995 shows white.
