david, with reference to the aug 82 sam article on the rhodesian/zimbabwe af,the profiles only make reference to the u/wing serials on a/c with raf roundels with 3 assegai's. however reading article it seems probable that serials were still carried in one assegai period, but states that from1976(half way through lion roundel period)all markings were removed.and only rear fuselage serial applied when yellow bird was adopted. hth chris
