Sherman M4A3E8
A35 Another view of the perforated screen. see the drivers hatch. Upon inspection I found that the hatch when closed did not line up with the opening. I feared a bent hatch. Fortunately it was the rubber bushing. These bushings were two steel tubes with rubber molded in between. All hatches had these bushing I guess to be a shock mount in time of travel with open hatches. Even the pistol port door had them.
