drgon47 is correct.... but...
Just to head off the question I feel coming.... the Mk V is H1, MK VI is H2 and H3.... but the peps based on the H2 game models are less detailed than the peps base on the H3 models.... more detail makes them slightly harder to build, but they will have more detail+++
You see my blog is the build of a MK VI from Slyfo's peps, and H3 game model...
