Spitfire Variant?

On page 15 of the December 2019 issue, the Spitfire photo labels it as a Mark VC. As far as I know these did not have 4-blade propellers or six direct exhaust stacks on each side. The props were all 3-blade and there were only three stacks on each side in which each stack was fed by the exhaust output of two cylinders each joined together (typical). Now I am not saying that there were not some special modified Spits, where, say, a 4-blade prop was installed or other mods. P.S. As a child I spent some years working on and flying my dad’s Vultee BT-13B, until it was sold to 20th Century Fox, one of many used in the movie Tora, Tora, Tora.
