Just found the unit in my "RAF and Commonwealth Squadrons ..." book. The Squadron code 'V' is at the rear on all aircraft, with the individual letter forward of the roundel, example 'T - V', serial number JK531.
Most aircraft appear to be in standard day-fighter camouflage, without the 'Sky' band, which is correct for this theatre. Some aircraft have had the band over-painted, and at least one aircraft, 'D - V' seems to lack under wing roundels. The tonal reproduction in the B&W photos suggests that the underside colour might be something other than Medium Sea Grey, possibly 'Sky', but this can't be confirmed, and may just be the effect of the light.
The tones also suggest a possible difference in the upper surface colours, as the grey appears lighter than normal in one photo, but again, this is probably the light.
