Nice profiles Wojtek!
I've only got a very brief history of the Squadron, which shows that they commenced their operations in North Africa in August 1940, and in December the same year, were involved in fighter sweeps over the Western Desert, with some defensive operations in Egypt, until May 1942.
They were then equipped as fighter bombers, with Hurricane IIB's and IIC's, being active in the ground attack role during the Battle of El Alamein, before moving through Libya, utilising captured airfields. When they reached Tunisia, the Squadron was again employed in the air defence role, with cover for coastal convoys being their main duties, and at this time received some Spitfire MkV's., with which they were completely re-equipped upon moving to Cyprus in September 1943.
A move to Italy followed in February '44, with Spitfire MkIX's, where they undertook fighter sweeps over Yugoslavia and Albania.
In April 1944, the Squadron were at Hornchurch, England, preparing for the Invasion of Europe, and re-equipped with Tempests in August '44.
On September 7th 1945, the Squadron was re-numbered 174 Squadron.
You might find more info if you do a 'Google' under '274 Squadron, Royal Air Force', as there are normally squadron histories available, either through the RAF Museum, or RAF archives (MoD), and probably through Wikipedia.
Hope this helps a bit, but it seems they didn't use Hurricane IID's !
