Colin says:
I can't put names to all the faces,I am crouched in the middle,I think it is Taffy Williams lying down,Dave Wray behind him and Arthur Milne behind Dave.
 I think the guy with the hat is Phil Clarke and the tall one in the tracksuit is Dave Cox.From the left is Tony Long and behind him I think is Roy Nieder,Gillham?
With camera, Pearson? Facing away tall guy with the cigarette a total blank and Dinger Bell with ???? on his shoulders.

Can anyone help as to who is who ?  

Harry Crick has sent following details: Surely the one with the cigarette is Jim Cowell, and the one aloft is Ian Forster.I may be wrong, Ian was in hut 353 (I think) with me in the first year
