Finished.
I built shell storage racks with 20 of the 155mm shells in the storage rack in the box along with tarps, wicker mats and tools but of course it's all hidden with the tarp on now.
I found a pic of this version with a cab roof so I built a frame from Evergreen 0.030 rod and added a tissue cab roof.
Then beefed up the two supplied plastic bows in the box with additional bows and bracing and added an tissue tarp over the box.
I'm beginning to hate individual track links when there are 108 pieces per side and only about 7mm long.
I didn't want to dirty it up too much so only a light gray wash and some chipping in places.
This will be the tow tractor for my Dragon 15cm howitzer and limber if I ever get around to building that one. It's a complicated build with lots of tiny photo etch.
