Wow, the Krupp 28 cm K5 E.. very impressive, both the original and the model you are building.
probably all of you know that the Leopold and his "twin", called Robert, were used in italy, where they got the names of "Anzio Annie" for the Leopold, and Anzio Express for the Robert.
I read and heard various testimonials from people who saw the two K5 E in action, and had to be really "scary".
lečo, i am very interested about this model, like others, i waiting new pictures. Good work!
