The Valentine VIII was the designation given to Valentine IIIs that had been upgunned to carry the 6-pounder anti-tank gun. The Mk III had introduced a new three-man turret, but retained the original 2-pounder gun. This turret had just enough space to carry the more powerful 6-pounder gun. A number of Mk IIIs were upgraded to carry the new gun. On converted tanks the coaxial machine gun had to be removed, and there was only space for two men. There was also only space for 53 6-pounder shells, compared to 60-62 2-pounder shells in earlier marks.
The Valentine VIII carried the 6-pounder Mk III, the first mass production version of the gun. The prototype and most later versions had a L/50 barrel (length fifty times the calibre), but the Mk III used a shorter L/43 barrel in order to simplify production. The Valentine IX and Valentine X used the full length 6-pounder Mk V.
The Mk VIII was powered by the same 131 hp A.E.C. diesel engine as the Mk III.
The Mk VIII was one of three versions armed with the 6-pounder gun. The Mk IX was an up-gunned version of the Mk V, while the Mk X was built from new with the 6-pounder.
The Mk VIII was used by the 6th Armoured Division during Operation Torch, the invasion of French North Africa.
