WW2 era royal Afghan army, under Nader Sah. Their uniforms show WW1 British and German influence, epecially the officers. No beards whatsoever. They carry ex British P14 Elfields, which they will replace with SMLEs & mosins (and standard WW2 battledress btw) after the war. Their helmets are German M14s they adopted in 1930 and they wpuld keep them until the 1979 communist takeover. Now they are sold as Alexander's helmets to tourists, with random bits soldered on. I read somewhere they were actually of Austrian make, I have no clue. The sole extant Ro.37 sits at the grounds of the Italian embasy in Kabul. The only picture I found of one was a silver one during construction, at the factory, in Italy. The Hawker Hinds and 8 older Harts were used extensively during the 1944-1949 Safi revolt.
In the old pictures, the Afghan army looks sharp and the country looks suprisingly civilized.
