WK 518 was on U.L.A.S, 71/72 with yes, black prop with (eroded) yellow tips.......
Haraka - the 1971 issue of the Painting Guide calls for red/white/red bands (all measuring at 2", except the outboard red which was 2.5") on the face, and 6.5" yellow tips on the rear - but some examples still had yellow tips on both sides years later!
