Thomas Reginald Part was known as Reg by my grandmother Blanche.  They were engaged but the marriage was never to be.  Reg sent the photo to Blanche in 1918 from Belgium.  On the back he asks "Is this anything like the chap you used to know years and years ago?" He explains the armband or "brassard" was used as a pass to allow access anywhere for "signals".  My family has other correspondence from Reg dating from before the war.  This includes a poem in Esperanto as both were interested in this "universal" language.
