The Cromwell tank was Britain's entry into modern age tank design. Previous types had an old fashioned philosophy of both, design and technology, being either undermotorized or underarmored or outgunned. In many cases, all combined. Until the appearance of the Cromwell and its derivatives, the British armored forces had to rely mainly on a great number of vehicles supplied by the Americans. It served as the starting point for many new tank developments that came later, during and after world war II, such as the Comet and Centurion tanks.
The model shown here is Tamiya's excellent kit of this very important English tank. It's very nicely detailed and in my oppinion can be built as it comes, straight out of the box.
