Squadron or Group I.D please.

Hi all.
Anyone out there in Interweb land, have a idea on which Squadrons or Training Groups these particular aircraft are from. Any info greatly appreciated. VV542 was 14 sqn then it transfered to 130 sqn, but i cant find anything to back up the 2 squadron colours.
No idea where XE849 originated from but it eventually went to St Athan, as a GI airframe.
