I, and others, have used the one for the Princess Coronation R8117, on the Princess Royal classes.

R8110 Castle - Grange Class, Star Class.
R8116 S15 - King Arthur N15, Lord Nelson, B12.
R8115 Merchant Navy - West Country, Battle of Britain.

R8106 A3 - Peppercorn A2, B17.
R8107 A4 - Class P2, Duke of Gloucester.
