Made a test order of two models. The Mobile Artillery and the Infantry Support Tanks. They are resin with metal parts and fit together excellently. You can just see and feel the lines where the master has been 3D printed but that doesn't make the model any less appealing. I am very happy with them, good quality at a good price. I have ordered 2 more Mobile Artillery and 3 Steam tanks with 4" guns for my Canadians.
On with the Pictures. In the component parts
Size comparison against AD stuff and Black Hat miniatures Prussian tanks. There are just dry fitted together.
