Blenheims of No 1 A.G.S. Pembrey

Could anyone point me to photos of any of the below Blenheims of No 1 Air Gunnery School at RAF Pembrey in 1941?

?6241
?6006
?6348
?6245
?6514
?6276
?6337

These are the aircraft that Sgt Gordon Cox, Wop/Ag 13 Sqd, KIA 26.06.1942 flew in between 23.07 and 31.07.1941 while training as an Air Gunner.

TIA,

Walter
