I have recently revisited the AVT Model 270 that was in his "B" version through several years. It is an all-terrain vehicle whose wheels are moved by chains. I improved the vehicle and added some accesories like lights, ladders, standing platforms and a prominent external fuel tank. This was version "C". Going even further, I changed the pneumatic wheels for an all-steel spring blade wheels of increased diameter. This is model "D". Weathering was done using layers in Photoshop.
