>>6759447I might as well post the finished thing, here's the artillery piece with leftovers and extras.
I actually kind of like it. Elevation is adjustable by fiddling with the bits on the sides, though it's a pretty fragile assembly. The 'legs' attach together and the wheels can be pivoted down for travel. Then the barrel falls off because it's only held on by a single stud. Extra compact travel mode, totally a feature and not shit design.
The set has some neat recolors like technic pins and small bushings, bars, t-pieces and others in pearl dark gray.
