Now that I’ve mostly recovered from COVID, I’ve felt up to doing some more modelling. First, more painting on the tracks for the BARV, followed by the markings and installing those tracks:
The markings aren’t intended to represent any particular vehicle, though Resicast gives you decals for three different ones — except the instructions for them are pretty much unusable:
I therefore went looking for photos of BARVs, which left me with the impression that they seem to have all been marked differently, and then used some of Resicast’s decals as well as a registration number and stars from Asuka’s Sherman V kit. The number is of course wrong for a Sherman III, but 1) who’s going to notice? And 2) half hidden by the ropes it’s hard to read anyway 
The tracks were painted by adding a wash of dark red-brown over the grey I had sprayed them, followed by drybrushing with a medium metallic colour, and then with a silvery one. Then a light wash of a sand colour, and I also used that same paint plus acrylic texture gel to simulate sand on the bogies and the hull front. Not much, because I see this as the result of driving through dry sand for a short distance — not much would stay on the tank when driving through water.
The rope on the front is still loose. It is connected to the 2-pounder recoil cylinder, but I haven’t decided what to do with the free end. I think I’ll keep the rope in this colour, though, to give the impression that it’s dry, unlike the ropes along the hull sides.
