Here is one of my christmas builds, although I bought it some years ago! (one of those you build before the christmas models arrives and makes you forget older unbuilt models). I searched for a long time for a camo and I finally went for a woodland camo used for BA-10s, adapted to both the tank and the gun.
At one point I added too much inkings and weatherings, and I had to "clean" a bit the tank to don't make it look like it has been taken out from a lake!
The crew is painted representing a reconaissance camo, although it ended up looking too much like the 60s uniform. I modified all the original poses as I didn't like them all being just seating on top of the tank doing nothing.
