Thanks, Jeff. I am trying to learn the way of the M4 Jedi. So this would be considered an A3? I have got myself a Mato M4A1 (76) W. It has the cast hull, but I have also seen this same tank with the HVSS. What would it be? M4A1 easy 8? I am torn between rebuilding it as a M50 Super Sherman or leaving it as a WWII Sherman?
