The 1953 Review programme showed  three badges which were clearly to do with the second world war and the shortage of aircrew because of enemy action.  The badges are:-

The text below the three pictures reads:-
Worn on blue uniform [other than working dress] by CPO's on the cuff of the left sleeve ¼ inch above the centre button, and by other ratings 1½ inches from the end of the left sleeve, or 1½ inches above the point of the left cuff of jumpers with cuffs.  On blue serge working dress these badges are  worn above the left breast pocket of the blouse.  On white uniform they are worn 1½ inch above the left breast pocket of the tunic, or immediately above the top row of medal ribbons.  They are not worn on tropical shirts.

So these are rating pilots, and aircrewmen [observer] with a crown above their badge meaning that their job is substantive fully equating to officers for flying duties.  The third badge is one we are familiar with, without the crown, and is worn by a rating, any rating, who is qualified for aircrew operator duties, but does not have a command function.

By the time the 1977 Review arrived, rating pilots had long been a thing of the past. The programme showed just the well known badge mentioned above for ratings aircrew.
