It is not known for sure when SAS insignia was first worn (Some of the original members who fought in North Africa claim it was before their first operation). The design of the SAS cap badge (Known by many rather erroneously as the "Winged Dagger" when it is in fact actually supposed to be a representation of King Arthurs famous sword Excalibur) was made by Sgt. Bob Tait (There had been a design competition in the unit which he had won). The motto "Who Dares Wins" is credited to David Sterling. While the design of the SAS wings can put down to Jock Lewes who is said to have been inspired by a fresco of an ibis (Sacred Egyptian Bird now thought to be extinct) in the foyer of Shepards Hotel in Cairo.
