Mickl G was series of prototypes, about 8 were built, none of them very sucessfull. Look here: http://home.mit.bme.hu/~tade/pages/drawings/lap1.gif (top plane) I have some photos. There are no good plans of that airplane, but about 10 photos exist, and so building a model is possible. One of these planes was armed with 75mm gun. Cheers! G.
