In the light of the Mk VI/Mk V** confusion, I thought I'd put this gent's email on here. He was most pleasant and helpful over the Mk IIs at Arras, and corrected the captions.
He's Geoff Spender, Assistant Curator, email:
gspender at iwm.org.uk
I've got a bit of a backlog that I must send to him when I get time.
