Well, yes, the "A-designation" of a Sherman tells you what engine it used. Unlike many other tanks, Shermans were produced in parallel lines because of engine availability not because they were more modern versions.
So the M4 and M4A1 only used the radial engine.
The M4A2 used the twin diesel engines and were used by the Marines and lend lease to Soviet Union.
The M4A3 used the Ford GAA engine and became the standard US tank in the later stages of the war.
And the M4A4 used the Chrysler multibank engine. It went to the UK, but they called it the Sherman V (or Roman numeral 5).
The Brits called the M4 the Sherman I, M4A1 Sherman II, M4A2 Sherman III, M4A3 Sherman IV and the M4A4 the Sherman V.
So the Tamiya M4 Sherman early can only use the radial engine. None of the Shermans are "pre-war" because they all came after the start of the war.
The radial engine Sherman was used during D-Day in the M4A1 Duplex Drive amphibious Sherman.
The M4A1 was also used Post War in the US, by Allies and many other nations. The Radial engine was used in the latest M4A1E8 (76) tank.
