The earlier scan-based FOTW version shows a white flag with a red lozenge, yellow and red edging and white PR letters. Rosanoski’s comparison with another image from the same source finds no yellow and says the letters should stand upright rather than angled, an apparent display problem in those editions.
The corrected upright version is supported by US Navy 1961, which also gives the funnel a black top. Mitchell omits lettering from the funnel diamond, presumed to be an error.
