The basic airframe dimensions of the Spitfires were unchanged up to the Spitfire IX except the nose section and radiator configuration. The loading table is attached, some parts rewritten for clarity. It's for the Spitfire Ia and Ib but the CoG locations are exactly the same for the Spitfire V (as refered in the right corner of the table).
The exact values of the CoG location are following at accuracy of two decimals (verified from drawings and RM 2525), these are values by RAE and slightly different as given by NZtyphoon because mean aerodynamic chord is at different position, datum line being the same:
The lenght of the mean aerodynamical chord is 78.54"
The datum line is 18.65" behind the leading edge of the mean aerodynamical chord
The datum line is 23.60" behind the leading at the wing root
The CoG of the NACA tested Spitfire V was 31.40" behind the leading edge at the wing root and 7.80" behind the datum line.
