I didn't get much done last week, because of the heatwave, but prior to that I had been making some progress that I hadn't yet shared...
This is Tonk #2:

I was thinking of making this one Evil Sunz.* I think that suits the low-slung hull.
I'm not so sure about the turret. (Unfortunately, while the turrets can be swapped from one hull to another, they don't always fit so well - particularly where you want them to rotate.) At least the sides of the turret will give me space to put a sun glyph.
I ordered a WFB orc shield sprue off eBay for that. (I'm sure I already have some somewhere, but it was likely quicker and easier to buy some more than to find them...)
And this is Tonk #3:

As you can see, this one is a Bad Moon.
The picture shows the rear, rather than front. I had a spare exhaust piece from some ork sprue (Trukk perhaps?). I trimmed it down, but then it turned out to fit quite nicely from a screw hole underneath and up the back of the tank.
*I'm not sure whether Grotz really belong to the klans, but I assume they would imitate them. Anyway, my plan is to have each tank a different klan, so they're clearly distinct for game play purposes.
