Many thanks to rpchambe, rh142 and rogissimo. I've now got them both.
If the r is right in 30ac, is my answer of redcaps right? I can't think of anything else that fits R?D?A?S.
Still can't get it and it is the last clue for my wife and I. We have T_N_H_N and even adding THAN cannot get anything with MNO in either direction. Cannot get anything if the 3rd letter is wrong either. Have we got the right letters?
