Volume II: Insignia of Royal Naval Ratings, WRNS, Royal Marines, QARNNS and Auxiliaries Rank and Rate  (English, Hardcover, Coleman E C)

With the exception of the royal marines, who adopted light infantry rank insignia from their earliest days, the Royal Navy was slow to introduce distinguishing rate badges for those serving on the 'lower deck'. Even when they were introduced, in 1853, the corresponding introduction of a uniform was still four years away. As for officers, the design and arrangement of buttons also played a part in distinguishing one rating from another.
