I have been working on the base, for which I could try some armour modelling skills on the Maxim gun. Groundwork itself is just in basecoat.
The gun is a very crisp 3d print from Alex of Castle Miniatures. By sizing the MG34 it turns out Jeffs model is 1:15 scale, to which scale the Maxim was printed.
Some rough pictures below to give an idea of where this is headed.
