The top picture shows a reconnaissance Spitfire PR Mk.XI. The bottom engine cowling of the Spit didn't have anything in common with the Vokes filter. There was a larger oil tank mounted inside. Therefore the cowling was more bulged.
A lot going on with the second Spitfire in the first post which begs for a lot of questions. 1) standard desert camo with red spinner? B) white 18" QP✪?X 3rd) 6 stars and bars with red surround? Ω) whats going on with the star and bar on the fuselage? Is there a panel removed? ½) newer rudder? and finally, Mk IXe? Thanks in advance for any or all answers.
