Off topic and deep in the realms of trivia; however,
I understood that 600(City of London) Squadron Royal Auxiliary Air Force had the unique privilege of parading 2 squadron standards (one official and one 'unofficial' that should only be paraded within the boundary of the City of London). I did not believe that either of these standards was a Queen's Colour - it is certainly not listed as one in AP3327. However, the picture on the Squadron's website shows the standards' escorts and Warrant Officer dressed as if they were in a Queen's/Sovereign's Colour Party - ie sashes worn by escorts and sash and sword worn by WO. Is the picture of the Squadron’s 'unofficial' standard being paraded alongside the Sovereign's Colour for the Royal Auxiliary Air Force or have the Squadron decided to add extra ‘bling’ to the escorts to their Squadron standards.
Dull references from AP1358
