I'm building a Death Korps of Krieg army and plan to utilize field artillery pieces, specifically the Earthshaker Cannon. I'm investigating less expensive alternatives and stumbled across the following link: TRUMPETER GERMAN 15CM HOWITZER | MILITARY 1/35 SCALE | TRUMPETER | Plastic Kits | Catalogue | MarksModels. Visually it matches the Earthshaker quite well. It is in 1/35th scale. There are lots of posts on various 40K boards comparing 40K preportions to plastic model scales for vehicles and infantry, but none that I can find on field guns. Has anyone ever converted/substituted historical models for IG guns, and if so, what scale have you found is most accurate? Thanks much.
