In regard to the Spitfire C in the background of Joe Willis' "Hurricane" pic. I'd hazard a guess it is one of the Mk VIs taken to the middle east to do the job that was eventually done with the modified Vbs & later converted into PR Spitfires, though whether retaining armament or not I don't know. Rising decals did a set for mediterranean Spitfires which had decals for one of these BS124 A as seen here www.risingdecals.com/72-037/RD_72-037.htm. a little over half way down. The Spitfire C in the background of said photo seems to have several features which would indicate it may well be one of the other MK VIs, such as a 4 blade prop, possibly black as also appears to be in these photos of BS124 www.network54.com/Forum/149674/message/1280014186/Spitfire+Mk+VI+%28Trop & www.network54.com/Forum/149674/message/1280030366/Here+is+another+shot+of+the+Mk+VI+%28trop%29 as well as the horizontal strengthening bar in the clear section behind the domed part of the canopy which appears to be peculiar to this mark. The seriels of those I can find are BS106, BS124, BS134, BS149 plus at least one other. Steve.
Although Bob Swaddling's post suggests BS124/A is possibly a modified Mk V, I have BS124 as a Mk VI in my records. Note the intake for the cabin pressure supercharger on the starboard engine cowling.
I wonder if the 'our' in the original caption "Our Spit 6 - our anti-shufti kite" refers to his 417 Sqn RCAF or the Desert Air Force in general.
