The Vampire is an F1 and wears 3 Sqn codes (J5). That unit operated Vampire F1s between Apr 48 to May 49 at three German airfields; Wunstorf, Gutersloh, Lubeck and then back to Gutersloh where it re-equipped with Vampire FB5s in May 49.

The Mosquito is, I think, NF 30, NT508 (if I have read the underwing serial correctly), possibly of 616 Sqn, but that is a guess as no unit markings are visible.
