AFV Club 1/35 M4 Sherman Medium Tank This is a 1/35 Scale model of the M4 Sherman Medium Tank. This model has horizontal volute spring suspension. One of the most significant updates to the World War 2 M4 was the fitting of HVSS suspension, giving it a smoother ride. It worked so well that versions of the American Sherman with the Horizontal Volute Spring (HVSS) set up were sometimes called the “Easy 8” because the standard gun tank was labelled the M4A3E8. The M4A3E8s Shermans equipped with the new suspension & widened tracks started to see action during the Battle of the Bulge.
