This is RAF Heliopolis in Cairo - not the same airfield as Almaza (HEAZ). Some of the buildings look more modern than the aircraft, but then the Valentia looked outdated from the outset. Nevertheless, the type served well into WWII, sometimes still uncamouflaged. The second machine, K3605, even flew a bombing sortie against Italian troops at Sidi Barrani, Egypt in November 1940. The third, K3163, has its serial painted as KR3163, being a rebuilt Victoria. These are No 216 Sqn aircraft.
