The flag has blue and red quarters and a white, concave-sided diamond bearing a red M. L166 shows the flag as a broad band on a white funnel; Rosanoski considers the white a probable printing error, stating that the funnel was never white.

L167 shows a black funnel with the flag reversed, apparently omitting the white edging to the band.

L168 adds the white edging above and below the band and appears to be the correct version. The WSS history describes a square containing a white lozenge with a red M and alternate red and blue triangular corners. Rosanoski notes that a square would imply a panel or a very narrow funnel.
