Regarding the"Executive Curl" which seems to be a source of confusion among some, since it is known that the curl was only on the uniforms of "qualified deck officers". I have read a few sources which state that the Junior Officers (Pitman, Boxhall, Lowe and Moody) would therefore not have had the executive curl on their uniforms. In fact, every deck officer on Titanic had their Master's Certificate, likely gained by experience in other lines (Captain Smith qualified as Ordinary Master sailing cargo vessels for A. Gibson & Co.).That said, other officers wore the same uniform, for example, Chief Engineer J. Bell also had four stripes on his uniform coat, but since he was an Engineering Officer and not a Deck Officer, he didn't have the executive curl, just four straight stripes. Likewise Chief Purser H. McElroy also had stripes without the executive curl, being the Officer In Charge of Titanic's Victualing Department.In the case of the Pursers and Chief Stewards, there may have been a secondary color between the stripes, but I am not sure. Information on that would most likely be found in the British Royal Navy uniform regulations of the era. White Star Line seems to have, for the most part, taken those regulations on board, which only makes sense since many of their officers were Royal Navy Reserves as well. Thus far I have been unable to find a good source for Royal Navy Uniforms c. 1912, and if anyone could point out a place where I could find them, short of traveling to the UK and haunting libraries, that would be much appreciated.
