Hi Steve, Black lanyards for the QOR were approved in 1949. Documentation indicates the QOR wore a black cord prior to the FWW and switched to the red cord immediately after that war. In the post SWW era they applied for authority to wear the black cord again. It was explained that the regiment wished to revert to the traditional black rifles cord. An officers and other ranks quality was approved, with the officers being a double cord and the other ranks a single. Not sure of the history after the mid 1950's.
