On the imagery I am checking there are actually 3 single seat Jags - the one at the back in the blue and white scheme and two in the main park in “operational” schemes.
Demobbed (no “last updated date”) suggests these here are not ex RAF.... it also confirms at one stage three meteors - one NF11 and 2 TT20s.
The lightning, as already indicated is XM178 and the only other U.K. “bird” is a Harvard IIa ex EX580.
