The most distinct armband frequently seen in photographs is the white over blue signallers brassard. A qualified signaller also wore a pair of brass crossed flags on his left forearm.
The armband made a signaller recognisable at a distance.
Some wore one on each arm.

Some Officers wore plain coloured armbands but not often in photographs.
