T-34/76E - Production model of 1943 with a commanders cupola.
T-34/76F - Production model of 1943 with a cast version of the T-34/76D turret.
T-34/85 - Production model of 1943 with a 85 mm gun and improved turret.
http://www.soviet-empire.com/arsenal/army/tanks/t34.php"The T-34 design evolved throughout the war: the T-34/76B had a rolled-plate
turret; the T-34/76C had twin roof hatches instead of the one
large hatch; from the winter of 1942/3 the T-34/76D introduced
a hexagonal turret, wider gun mantlet and jettisonable exterior
fuel tanks; the T-34/76E added a cupola on the turret for the
commander and was of all welded construction; the T-34/76F
Had a cast rather than welded turret; during the winter of
1943/4 production of the T-34/85 began and used the turret of
the KV-85 tank which included an 85-mm main gun plus space for
an additional crew member so the commander did not also have
to fire the gun."
