Action dated 24 September 1977. Hellman of Hammer Force cover, artist unknown. The pose is reminiscent of a splash page featuring Karl Schafft, everyone's favourite member of the Abwehr, by Francisco Fuentes Manuel that had appeared in Warlord in February that year.
A great Code-Name Warlord splash page, featuring Peter Flint's recurring rival Karl Schafft. Art by Francisco Fuentes Manuel from Warlord No
Both are similar to an Airfix WWll German Paratroops figure that had first been released in 1976. The figure is in a running pose with his left leg raised off the base and holding a MP40. He's the main figure on the box art, which I think is by William Stallion, below (but facing the opposite direction) and fifth from the right on the row of figures at the bottom. It's possible both drawings were based on the Airfix figure as I'm sure artists then did base a lot of drawings on model kits and the like.
