These are the Hasegawa Macchi C.202 and C.205 models, including the 1/72 kit shown immediately above. These ever popular kits are let down by poor interior detail but there are numerous aftermarket sets to help you improve these areas, such as cockpit sets by FM Details, True Details, SBS and Jaguar for the 1/48 kit. Eduard also do a fully detailed 1/48 wheel well set and Ultracast have resin upgrades for the seats and exhausts in this scale too. Misterkit did very nice detail sets for the 1/72 kit including replacement fusealge parts! Because Hasegawa shared most parts across the 2 types, check your references to make sure the right detail is either addded or removed accordingly. For example the cannon armed C.205 had slightly different wing panel detail compared to the C.202, so this will need to be dealt with. There were also slight differences to the elevators and various bulges around the front fuselage too numerous to explain in detail here. Maurizio de Terlizzi has covered this in various publications he has authored.
