Pardon me if I’m wrong but that looks like a Meteor F. 3. It’s got curved wingtips, whilst the wings themselves continue for a fair bit outboard of the Derwents. It also appears to have the smaller nacelles of early and mid-production F. 3s (although the last batch were fitted with F.4 nacelles). Given that 222 were equipped with the Meteor 3 for a while post-war, it doesn’t seem unlikely that it is an F. 3.

It’s got F4-style nacelles (continue back and forward of the wings, but the curved wing tips don’t neccessarily make it a mk 3.

The first few mk 4s were produced with the ‘F3’ style wing tips (making it virtually impossible to tell apart late F3s and early F4s) – EE525 was apparently the first with the ‘clipped’ wings.

As for a Meteor F4 in camouflage with codes, there is a picture of EE464 in full Day Fighter scheme colours in April 1946 wearing the codes ‘ON-F’ of 124 Squadron (albeit apparently serving with 56 at the time the pic was taken)
