Thanks for that John.
Along with the Sextons, two carriers. (as well as the bike, half-track, Sherman, etc) The carrier on the right appears to be a MK-I* updated to MK-II style, repositioning the off side MK-I* headlamp complete with original mounting base to the more familiar MK-II position. I am pretty sure there is another image floating about with that carrier WD number showing, CT201555.
These fortunate gunners get to finally go home.
