Sorry no photos of it unpainted exist. I should have taken some but didn't think of it at the time. If it helps. Its all plastic card except for the barrel, that is a couple of old cut up pens Shaped up with green stuff. And all of the details are made from green stuff.
The mortar is very impressive, really captures the "dwarven design" spirit. I would actually like to see unpainted version to see how it was scratch built (i.g. what is green stuff, what is cutted from plastic card etc.). Great job anyway.
