ZG752 - RAF 100 markings
ZG771 - Marham centenary marks (black spine, fin and radome).
ZA612 - standard grey scheme.
From what I can tell ZG752 and ZG771 are practically hangar queens at this point. 771 pops out occasionally and 752 hasn’t been seen for a few months, at least not by those of us outside the fence!! :-)
