They're putting the Spitfire ON the carrier? Was this towards the end of the war you think?
The closest one is wearing the serial NF539. It seems to be the K code letter and a trace of W on the fuselage The serial of the Spitfire behind her is NN339. Both serials indicate the Seafire Mk.III. According to the info I found via the net the Seafire III NF539 belonged to the 899th Squadron FAA. Judging by this all these Spits in the image are Seafires.
