This vehicle was the early production model of the Sherman tank, it had a welded hull, and a cast turret carrying the gyro stabilised 76mm Gun M1A1 with a squarer mantlet than the M4 . The vehicle was first produced in October 1941 and was derived from the earlier M3 tank chassis. It was driven by a Continental 400HP air cooled engine with the drive sprocket at the front, the track went under 3 double bogie wheels onto the idler, then back over 3 return rollers..

Hit probability is based on a static 2 x 2.4 metre panel at 0 degrees(vertical) at the range specified.
The data that has been used to create these records has come from Wikipedia, The Lone Sentry, The Bundes Archive
and numerous books and websites that have provided the detailed information that has not been available anywhere else. The
information we use to calculate the penetration tables, flight times and the hit probability comes from the Gun Calibre,
the Shell Mass(Kg) and the muzzle velocity, plus range reductions to allow for gravity and wind resistance. This calculation
originally came from a pre-war Krupp calculation which has been modified, and seems to fit the actual test results.
