This is my wip for this amazing weapon.
Got these blueprints from the-blueprints.com. The side and front views don’t match up so well so I am using the side and top view as my basis. With some other reference images and even found a walk around video which will help a lot with getting a feel for the Howitzer and be able to catch any small details.
