Brown 1995 gives J39, while Skipet shows its flag with a broader cross. Rosanoski describes the white field, blue cross and white star, noting that most sources place the star on a blue circle rather than a diamond. A cap badge clearly has straight diamond sides, but small illustrations can obscure the distinction. Discussion of a similar silver-bowl device favoured Jahre attribution without certainty; Rob Raeside regarded a website ship illustration as support for the circle.
Rosanoski presumes that Mitchell’s J187 funnel is wrong.
