Well, oddly enough, my friend Jim just brought along a box load today and included was...
you guessed it... a ribbonless BWM to:
539 Pte. J. Hennessey, Rif. Brig.
How's that for coincidence!?
(I have a "87" Indian Railways Afghan NWF 1919, but that I assume was a "militarized" civilian chappie).
Hard to imagine pre-war regulars in an outfit like the Rifle Brigade making it through the entire war.
