Incorporates a stopwatch holder at the top - this is the same type normally found within wartime aircraft. Has two sorbo rubber pads to the rear in order to make it more comfortable to wear. Fastens around the thigh using an adjustable leather strap that incorporates a fabric covered sprung section similar to those found on MK.III/IIIA goggles. Name plate riveted to the bottom 'Lieut.
